DOI:
http://dx.doi.org/10.1016/j.ympev.2011.04.002. ABS: This
study focuses on the phylogenetic relationships among ninety percent of
known Dolichopoda species (44 out of 49); primarily a Mediterranean
genus, distributed from eastern Pyrenees to Caucasus. A total of 2490
base pairs were sequenced corresponding to partial sequences of one
nuclear (28SrRNA) and three mitochondrial genes (12S, 16S and COI). A
relaxed molecular clock, inferred from Bayesian analysis was applied to
estimate the divergence times between the lineages using well dated
palaeoevents of the study areas. Molecular substitution rates per lineage
per million years were also obtained for each analyzed gene. Based on the
nearly complete species phylogeny, temporal patterns of diversification
were analyzed using Lineage-Through-Time plots and diversification
statistics. Alternative hypotheses about the colonization of present range
by Dolichopoda species were tested by means of Approximate Bayesian
Computation analysis. Results from this analysis carried out on the 90%
of known Dolichopoda species confirmed the previous ones based on
subgroups of species, suggesting the ABC analysis as a remarkable tool
in biogeographic studies. Based on these results, the distribution of
Dolichopoda species appears to have been shaped by the
palaeogeographic and climatic events that occurred from Late Miocene
up to the Plio-Pleistocene. Both vicariance and dispersal events appear to
have influenced Dolichopoda species distributions, with many processes
occurring in ancestral epigean populations before the invasion of the
subterranean environment. Highlights: A total of 2490 bp was analyzed in
species of the Mediterranean genus Dolichopoda. Molecular clock was
calibrated using well dated palaeoevents of the study areas.
Diversification's patterns were analyzed by LTT plots and diversification
statistics. ABC analysis was used to test alternative biogeographic
hypotheses. Results suggested the ABC analysis as a remarkable tool in
biogeographic studies. KW: Lineage diversification, Molecular rates,

DOI:
http://dx.doi.org/10.5038/1827-806X.40.1.3. ABS: Nitrogen
fixation was measured in situ for the first time by acetylene reduction for
a greyish mat composed of Scytonema julianum in cave-like
environments. Mat-specific rates (129.9-215.7 nmol C2 H4 m-2 s-1 for
daytime fixation and 65.1-120.6 nmol C2 H4 m-2 s-1 for nighttime fixation)
recorded in the Vapor cave differed considerably due to the energy
reserves stored during photosynthesis being exhausted and used in the
dark phase. The most influential environmental parameter for nitrogen
fixation in the Vapor cave is temperature in the daytime and nighttime
fixations. Nitrogen fixation by cyanobacteria may contribute considerably
to the overall nitrogen cycle in harsh environments such as caves.
Nitrogenase activity in Scytonema julianum was roughly 30 times higher
than that of Scytonema mirabile, which also grew in cave environments,
which is due to the characteristics of each site. The entrance of Vapour
cave (Spain) faces SE, measures 0.75 x 0.6 m and opens to shafts of a
total depth of 80 m. Its dimensions and environmental conditions (relative
humidity up to 100%; maximum temperature, 43ºC) imply that it is
isolated from external influences, and that the microclimate differs
substantially from that experienced externally. Nitrogen fixation, photon
flux density, relative humidity and temperature in the Vapor cave were
taken hourly over a 24-hour period in winter. KW: Caves, cyanobacteria,

ABS: Moonmilk, a microcrystalline secondary cave deposit, actively
forms on the floor of Krem Mawmluh - a limestone cave in Meghalaya,
Northeastern India. Due to the abundance of micrite and calcified
microbial filaments, we hypothesize that these deposits form as a result of
ongoing microbial interactions. Consistent with this idea, we report
electron microscopic and microbiological evidences for the biological
origin of moonmilk in Krem Mawmluh. Scanning electron microscopy
indicated abundant calcified microbial filaments, needle calcite, fibre
calcites (micro-fibre and nano-fibre calcite crystals), biofilm and

microbial filaments in the moonmilk. The total viable culturable microbes
showed high population densities for microbes in the moonmilk and
moonmilk pool waters. In vitro culture experiments, confirmed the
capability of many of the isolated strains to precipitate calcite and some
of the identified isolates belonged to the Bacillus sp. and Actinomycetes.
These results clearly support the biogenic nature of the deposits. KW:

Islands beneath islands: phylogeography of a groundwater
amphipod crustacean in the Balearic archipelago. BMC
Evolutionary Biology 11(July 26):221. ABS: Background:
Metacrangonyctidae (Amphipoda, Crustacea) is an enigmatic continental
subterranean water family of marine origin (thalassoid). One of the
species in the genus, Metacrangonyx longipes, is endemic to the Balearic
islands of Mallorca and Menorca (W Mediterranean). It has been
suggested that the origin and distribution of thalassoid crustaceans could
be explained by one of two alternative hypotheses: (1) active colonization
of inland freshwater aquifers by a marine ancestor, followed by an
adaptative shift; or (2) passive colonization by stranding of ancestral
marine populations in coastal aquifers during marine regressions. A
comparison of phylogenies, phylogeographic patterns and age estimations
of clades should discriminate in favour of one of these two proposals.
Results: Phylogenetic relationships within M. longipes based on three
mitochondrial DNA (mtDNA) and one nuclear marker revealed five
genetically divergent and geographically structured clades. Analyses of
cytochrome oxidase subunit 1 (cox1) mtDNA data showed the occurrence
of a high geographic population subdivision in both islands, with current
gene flow occurring exclusively between sites located in close proximity.
Molecular-clock estimations dated the origin of M. longipes previous to
about 6 Ma, whereas major cladogenetic events within the species took
place between 4.2 and 2.0 Ma. Conclusions: M. longipes displayed a
surprisingly old and highly fragmented population structure, with major
episodes of cladogenesis within the species roughly correlating with some
of the major marine transgressionregression episodes that affected the
region during the last 6 Ma. Eustatic changes (vicariant events) -not
active range expansion of marine littoral ancestors colonizing desalinated
habitats-explain the phylogeographic pattern observed in M. longipes.

Little is known about the hypogean fauna of Algeria, with studies mostly
dating to the beginning of the twentieth century (Gurney, 1908;
Racovitza, 1912; Monod, 1924; Pesce & Tetè, 1978); moreover, the
knowledge varies markedly among regions. In this study, we examined
the composition and distribution of the invertebrate communities in the
phreatic zone of the Tafna aquifer (N-W Algeria). Twelve wells close to
the Tafna wadi, ranging between 120 and 1100 m a. s. l., were studied
from May 2005 to March 2006. Many specimens belonging to 37 taxa
were collected, the most frequent taxa being Typhlocirolana sp., a
stygobitic Gammaridae species, Cyclopidae and Ostracoda. Other
crustacean species were relatively scarce, with discontinuous distribution,
being present only in a few wells. The taxonomic richness and abundance
of stygobitic crustacean communities were relatively constant over time.
The spatial distribution of stygobionts was mainly related to the
exchanges with surface water. KW: Tafna, Algeria, Stygobionts, Wells,

isolation approaches for fumarole deposit microbial community analysis.
Deposit samples were collected from steam vents and caves in Hawaii
Volcanoes National Park, Yellowstone National Park, and Lassen
Volcanic National Park. Samples were analyzed by X-ray microanalysis
and classified as non-sulfur, sulfur or iron-dominated steam deposits. We
experienced considerable difficulty in obtaining high yield, high quality
DNA for cloning: only half of all the samples ultimately yielded
sequences. Analysis of archaeal 16S ribosomal RNA gene sequences
showed that sulfur steam deposits were dominated by Sulfolobus and
Acidianus, while non-sulfur deposits contained mainly unknown
Crenarchaeota. Several of these novel Crenarchaeota lineages were
related to chemoautotrophic ammonia oxidizers, indicating that fumaroles
represent a putative habitat for ammonia-oxidizing Archaea. We also
generated archaeal and bacterial enrichment cultures from the majority of
the deposits and isolated members of the Sulfolobales. Our results
provide the first evidence of Archaea in geothermal steam deposits and
show that fumaroles harbor diverse and novel microbial lineages. KW:

response to high temperatures in adults of two cold stenothermal cavedwelling leptodirins, Neobathyscia mancinii and Neobathyscia pasai
(Coleoptera, Cholevidae) was evaluated by determinating levels of gene
expression of two members of the family of heat shock proteins 70 kDa
by qPCR. In both species, hsc70 mRNA level was constant with
increasing temperature, whereas a significant increase in the inducible
member (hsp70) mRNA was observed, higher in N. pasai. This difference
could be due to their in-cave distribution: N. pasai colonizes the cave
entrance where the temperature is more variable than the internal part
where N. mancinii is confined. These results demonstrated for the first
time the occurrence of a heat shock response in troglobite insects and
suggest the correlation between the intensity of this response and the
adaptation to the cave environment. KW: Cold stenothermal, Heat shock

The
subterranean mode of life always needs a high degree of biological
adaptation. The cavernicolous species usually get selected from those
which are preadapted with biological traits suitable for cave life and
finally occupied a separate taxonomic status. With the ever going
exploration of subterranean passages in Jaintia hills, till date several
troglobitic species have been recorded from this particular area. Cave
biota survey with respect to the explored subterranean passages of the
area was conducted in February 2011. Krem Bylliat (cave) is one of them,
measure horizontally 600 m having several openings. The cave is situated
in the boundary of two major rock formations, nearer to one of the main
tributary of river Kopili. Though, the cave is harbour of rich biodiversity,
it was found to be relatively impoverished in terms of troglomorphic taxa.
Possible factors, obviating the evolution of troglomorphy in this cave
have been discussed. KW: Pre-adaptation, meghalayan caves,

Perpetual darkness, high humidity with almost constant geophysical
factors are some of the abiotic factors which make the cave ecosystem
unique. For any species a high degree of adaptation is always needed to
thrive in such an ecosystem. Mammals in general have never adapted to
cave life but they can play a major role in the cave ecosystem.
Structurally, the Dandak cave has two distinct chambers that are
completely different from each other in several geophysical factors. Thus

both the cave chambers offer two distinct types of ecological niche. In the
present study we found that both chambers of this cave were dominated
by mammals all year round. Additionally, the group of mammals using
the outer chamber completely differs from the group using the inner one.
Possible geophysical factors responsible for such differences are

The
roosting microchiropterans mostly prefer caves and are highly sensitive to
anthropogenic disturbances. The caves of the Kanger Valley National
Park, is becoming day by day the most crowd puller spot for Central India
and due to which it often overruled all the laws of ecotourism. In the
present study, two microchiropteran species were found to roost together
in the caves of the Kanger Valley National Park, India with distinct
microhabitats. Rhinolophus rouxii was found in the twilight to dark zone
of the cave while Hipposideros cineraceus was found to occupy the more
stable zones of the cave and was highly sensitive to anthropogenic
disturbance. The population sizes of the bats roosting inside the two
major caves have been estimated and compared with the earlier available
records and this provides evidence of a decline in abundance. Further, the
gestation/reproductive phase of these bat populations was also found to
coincide with the period during which the caves remain under the highest
anthropogenic pressure. In the present study several aspects which could
threatened the existences of the cave bats have been noted and proper
strategy to re-establish their populations have been discussed by
maintaining more or less the tourist pressure intact in the caves.

proliferation has commonly been reported to occur on monuments, such
as crypts, churches, and caves, as soon as artificial lighting is used. In this
work we study the effects of UV-C irradiation on algae collected in
different caves in Dordogne (southwest of France). First, the effect of
UV-C irradiation was tested on algal cell suspensions during increasing
exposure times. After treatment, the photosynthetic capacity was assayed
using a polarometric method, and algal cell viability was then estimated
using a Trypan blue test after a rest period of 15 h. UV-C irradiation was
then studied on algal cells cultivated on a solid support consisting of
pieces of calcareous stone. Drops of concentrated algal cells were
inoculated on stone and exposed to UV-C radiation for 3, 6, or 9 h. After
this irradiation, half of the samples were submitted to a high white light
intensity (1400 µmol m-2 s-1 of photosynthetically active radiation, PAR)

http://dx.doi.org/10.1651/10-3450.1. ABS: Two amphipod
species, Niphargus ictus and N. frasassianus, which are endemic to
Frasassi Caves, Italy, possess morphological features typical of most
troglobitic species. Most notably they lack eyes. Although cave waters
flow directly into the adjoining Sentino River and N. frasassianus is
found within two meters of the resurgence, neither species is present at or
further outside the mouth of the cave, which raises the question of how
they avoid leaving the cave. It was hypothesized that these animals might
be able to detect light, and could use light cues to remain inside the cave.
Individuals of both species exhibited greater activity levels in the
presence of bright vs. low light levels. Neither species exhibited the
dorsal light reflex, but both showed weak negative phototaxis when
exposed to bright light directed at them from above and below. N.
frasassianus, tested in an apparatus that permitted them to travel freely
between bright or a low lighted areas, demonstrated negative phototaxis.
The results show that both species can detect light, and suggest light cues
may be utilized to remain in the caves. KW: Amphipods, cave behavior,

Microorganisms stand at the basis of every food web in subsurface
environments. We report here the presence and abundance of air and soil
microorganisms isolated from three caves in Pădurea Craiului Mountains
(NW Romania). We determined the density of aerobic heterotrophic
bacteria and various microbial physiological groups (i. e. iron reducing
bacteria, ammonifying bacteria, denitrifying bacteria and air
staphylococci) in air and soil samples obtained from the three caves. The
largest density of aerobic heterotrophic bacteria was detected in the
atmosphere of Peştera de la Vadu Crişului, a cave most visited by the
tourists, and the smallest in that of Peştera cu Apă din Valea Leşului, a
cave that is rather inaccessible to regular tourism. The entrance zone of
all three caves contained more air microorganisms then the median and
profound zone of these caves. Iron-reducing bacteria, ammonifying and
denitrifying bacteria were present in the atmosphere of all three caves. No
staphylococci were detected in the air of the three caves. The soil
microorganisms prevailed in large number in Peştera de la Vadu Crişului,
while their smallest density was registered in Peştera cu Apă din Valea
Leşului. The ammonifying and denitrifying bacteria dominated the soil
microbial community in all three caves. The density of aerobic
heterotrophic bacteria was largest in Peştera de la Vadu Crişului, while
this cave contained the smallest abundance of iron-reducing bacteria. The
largest density of iron-reducing bacteria was instead registered in Peştera
cu Apă din Valea Leşului. KW: Air and soil microorganisms, cave,

in central New York State in February 2006. Since 2006, WNS has been
reported from bat hibernacula across much of eastern United States and
adjacent Canada and has been associated with a dramatic decline in the
populations of hibernating bats in the northeastern U. S. We are only
beginning to discover how these declines are manifest in changes in
summer bat abundance and activity at local scales. A 3-year (2004-2006)
acoustic survey showed that the forested watershed of the Quabbin
Reservoir in central Massachusetts supported an abundant and speciesrich summer bat community. In 2010, 4-years following the initial
occurrence of WNS, a re-survey of the same habitats and sites found a
72% reduction in bat activity on the watershed. This is the identical rate
of decline reported from cave hibernacula surveys (73%). This decline in
summer activity levels is most likely a consequence of WNS-caused
mortality. The impacts of population losses of this magnitude of a once
widespread and abundant taxa are unknown but are presumed to be
ecologically significant. KW: Acoustic survey, AnaBat, Myotis, Summer

Osmoregulation in Hypogean Populations of the
Freshwater Amphipod, Gammarus pulex (L.). Journal of
Crustacean Biology 31(2, May):332-338. DOI:
http://dx.doi.org/10.1651/10-3336.1. ABS: The freshwater
amphipod Gammarus pulex is widely distributed in freshwater streams
and rivers of Europe. This amphipod also has isolated hypogean
populations, which are transparent in appearance, suggestive of
adaptation to their cave environment. Since cave habitats are often food
limited, physiological adaptations have been observed that reduce the
energy expenditure of cave organisms. Osmoregulation is an
energetically expensive mechanism that allows gammarids to survive in
fresh water. This study tested the hypothesis that differences in
osmoregulation existed between hypogean and epigean populations of G.
pulex. The osmoregulatory parameters measured were haemolymph
cation concentrations, water and sodium fluxes and gill Na+/K+-ATPase
activity. The hypogean G. pulex had significantly lower haemolymph
sodium and potassium concentrations, but had a significantly higher
haemolymph ammonium concentration than the epigean G. pulex. The
low food availability in the hypogean environment was considered to be
the underlying cause for these differences in haemolymph ion
concentrations. KW: Amino acids, ammonia, caves, Gammarus pulex,

the impact of bats on archaeological structures. Archaeological sites were
checked for bats or bat sign (i. e., guano or urine stains) and
recommendations were made regarding bat use of the archaeological sites
at each of the monuments. Guano was found in all the archaeological
sites checked at Montezuma Castle National Monument. We found ≤3
individuals of two species day roosting, and approximately 40 individuals
of seven species night roosting in the five-story cliff dwelling at
Montezuma Castle Unit. A maternity colony of Townsend's big-eared
bats (Corynorhinus townsendii) was roosting in Swallet Cave at
Montezuma Well Unit. Bats used the crevices in the rock face above the
cliff dwellings for roosting at Tonto National Monument. We found small
amounts of guano in the tower room of the pueblo at Tuzigoot National
Monument. Bats were not causing damage to the archaeological
structures.

populations from Mexico, Belize, Guatemala, Honduras, Costa Rica, and
Colombia was analyzed by capillary gas chromatography coupled to mass
spectrometry; linear discriminant analysis was used to help elucidate
population structure. Vector populations segregated into five distinct
groups; specimens from Yucatan Peninsula, together with those from
Central Mexico, Central America, and Colombia corresponded to
different T. dimidiata subspecies, a putative different species comprising
insects from Belize, together with an isolated population collected at bat
caves in Guatemala. The analysis revalidates the earlier division of T.

was to investigate levels of genetic divergence across populations of
Bathynellacea, a small crustacean group that lives exclusively in
groundwater, in order to evaluate the extent of cryptic speciation in
morphologically constrained clades. Partial sequences of cytochrome
oxidase I (COI) have been obtained, for the first time in Bathynellidae.
Specimens analyzed of the genus Vejdovskybathynella were obtained
from six populations morphologically assignable to a single species; all of
them are located in different areas of one of the largest karst systems (110
km of galleries topographied) known in Spain. The analyses of molecular
data demonstrate the presence of three highly divergent genetic units,
possibly corresponding to undescribed new species. The results of this
study provide the first molecular data that complement morphological
knowledge in order to address phylogenetic studies to try to resolve the
relations between genera and species of the Bathynellidae family. We
conclude that the evolutionary scenario of this special group of
subterranean crustaceans cannot be revealed only by using morphological
information due to the presence of very old lineages of cryptic species, as
has been brought to light with the molecular data obtained here. KW:

Background: The cave fauna of the Brazil is poorly documented, and
among the insects those live or frequent caves and their adjacent
environments phlebotomine sand flies call for special attention because
several species are vectors of pathogens among vertebrates hosts. A new
species of sand fly from Minas Gerais is described based in females and
males collected in a cave of the municipality of Lassance. Results: The
morphological characters of the new species permit to include in the
Evandromyia genus, cortelezzii complex. This complex consists of three
species: Evandromyia corumbaensis (Galati, Nunes, Oshiro & Rego,
1989), Evandromyia cortelezzii (Brethes, 1923) and Evandromyia sallesi
(Galvao & Coutinho, 1940). Conclusions: The new species can be
separate from the others of the cortelezzii complex through
morphological characters of the male terminalia and female
spermathecae.
Abundance and species richness of terrestrial cave invertebrates are not
well known but are thought to be constrained by nutrient (food) supplies.
A standard sampling procedure for collecting cave invertebrates does not
exist. The majority of cave systems in the southeastern USA (e. g.
Alabama and Georgia) have not been extensively sampled for
invertebrates. We tested a baited ramp-pitfall trap for collecting terrestrial
invertebrates from caves and investigated whether macroinvertebrate
abundance and species richness follow total organic matter (TOM) levels
from cave soils. In 14-day sampling periods, we captured 21204
invertebrates from 14 orders comprising at least 44 species from five
caves in north Alabama and Georgia. Diptera was the most frequently
captured order, comprising 18 species and over 91% of our captures.
Overall, our traps were successful at sampling terrestrial invertebrates
from caves; however, species richness and abundance did not always
correlate with TOM concentration. KW: Caves, Alabama, Georgia,

investigates the ecological parameters of the sand flies present in
Ibitipoca State Park, Minas Gerais, Brazil. During 2009, systematic
collections of sand flies were made monthly using HP light traps installed
at five sites, including three natural settings (a cave, riparian vegetation,
and a rain forest), the tourist and researchers' accommodations, and a
surrounding domestic livestock area. In total, 161 sand flies (seven
species) were collected, the most abundant, particularly in the
surrounding domestic livestock area, being Lutzomyia (Psychodopygus)
lloydi (Antunes, 1937). Furthermore, a previously unidentified Lutzomyia
(Sciopemyia) sp. was prevalent in the cave environment. There are no
existing records of the occurrence of leishmaniasis in Ibitipoca State
Park; however, the some species of the subgenus Psychodopygus are
known vectors of Leishmania spp in Brazil. Hence, the presence of a
species of this genus in areas surrounding the park may represent a risk to
ecotourism and the local inhabitants. Our study shows the importance of
regular monitoring of the various areas used by humans to determine the
distribution and spread of sand fly vectors for preventive management to
forestall potential risk to health and consequent effect on ecotourists.

alabamae is endemic to subterranean waters in northern Alabama. Its
type locality is Shelta Cave, Madison County, and ostensibly conspecific
shrimps have been found in Bobcat and two other caves. Pollution and
other factors may have extirpated the shrimp from the type locality. In
Shelta Cave the species is smaller than the shrimp in Bobcat Cave and P.
ganteri in Mammoth Cave, Kentucky. Adult female P. alabamae (s. s.)
and P. ganteri are larger than males. Female P. alabamae with visible
oocytes or, rarely, attached ova, were observed from July through January
in Shelta Cave. Each female there produces 8 to 12 large ova, whereas
females of the population in Bobcat Cave produce 20 to 24 ova, and P.
ganteri produces 14 to 33 ova. Plankton samples taken in Shelta and
Mammoth caves yielded nothing identifiable as zoea or postlarvae.
Palaemonias alabamae and P. ganteri usually feed by filtering bottom
sediments through their mouthparts, but both sometimes feed upside
down at the water's surface. Although there is some overlap, the
compositions of the aquatic communities in Shelta and Mammoth caves
differ, and there are some major differences among the Alabama shrimp
caves. The stygobiotic fish, Typhlichthys subterraneus, is a known
predator on P. alabamae in Shelta Cave. KW: Cave shrimps,

DOI:
http://dx.doi.org/10.1016/j.revpalbo.2011.06.006. ABS: Cave
fossil records from the Patagonian steppe (Argentina) have been largely
used as a source of archaeological and palaeoenvironmental information.
Major uncertainties exist, however, regarding the degree to which the
fossil pollen assemblages from caves reflect past environments because
of the complex site formation processes and post-depositional bias.
Studies within caves from other regions have demonstrated that the
understanding of modern pollen taphonomy helps to recognise the record
bias improving thus the inferences. The present study therefore aims to
understand how modern plant communities are represented within two
caves at the Patagonian steppe and to establish the modern pollen
taphonomic processes. Cave pollen assemblages provided a good
representation of the local vegetation indicating therefore that cave fossil
pollen assemblages are a reliable source for inferring the past vegetation.
However, the modern taphonomic analysis pointed out that cave pollen
assemblages are not homogeneous but show spatial variability due to
different factors. Vegetation distribution, physiognomy and pollination
type, biotic transport and human disturbance were the major factors
affecting the cave pollen assemblages whereas orientation and
topographic position seemed not to be significant. Biotic transport caused
unexpected deposition patterns while animal and human post-depositional
disturbance the homogenization of pollen assemblages. Other factors
such as the cave internal topography, morphology and microclimatic
circulation might be determinant on floor pollen assemblages so should
be further investigated. Highlights: Modern pollen taphonomic processes
were studied at two Patagonian steppe caves, Argentina. Predominant
pollen deposition pathways are airfall and biotic. Biotic pollen transport
strongly alters pollen deposition patterns. Human and animal trample
disturbance lead to the homogenization of cave pollen assemblages. Cave
orientation and topographic position do not determine pollen deposition
within these caves. KW: Pollen, caves, taphonomy, Patagonian steppe.

spiders belonging to 25 families are known. One species, the linyphiid
Porrhomma convexum (Westring, 1861) was recorded here for the first
time in Greece. The 109 species are distributed in caves of different
geographic territories as follows: Thrace - 8 species, Macedonia - 18,
Epirus - 1, Thessaly - 6, Central Greece - 3, Attiki-Saronic Islands - 24,
Peloponnese - 15, Evoia-Vories Sporades - 1, Eastern Aegean Islands - 5,
Cyclades - 3, Dodecanese - 6, Ionian Islands - 23, Crete - 47. The largest
fraction of troglobite species were encountered mainly in the territories of
Crete - 15 species (5 of which are anophthalmic), the Ionian Islands - 4,
Thrace - 2 (both anophthalmic), the Attiki-Saronic Islands - 2 (both
anophthalmic), the Peloponnese - 2 (one anophthalmic), and Macedonia,
Thessaly, and the Cyclades - each with 2 species. The richness of the
troglobitic spiders in these regions strengthens the assumption that they
were major centres of speciation and evolution for the species of this
group. According to their current distribution, the established 109 species
can be classified into 12 zoogeograpical categories, grouped into 4
complexes (widely distributed, European, Mediterranean, endemics). The
largest number of species belong to the endemic complex (53.2%) and are
also the most characteristic and reflect the local character of the cavedwelling spiders. KW: Cave-spiders fauna, endemics, troglobites,

Mitteilungen 40(January), ISSN 1018 -4171. ABS: In 2005 a
team of Bulgarian zoologists started a project aiming to study the
invertebrates inhabiting the deeper soil stratum (euedaphon) and the
Superficial Underground Compartment (SUC) in Bulgaria. In the course
of a four-year sampling, a total of 52 species of spiders were caught from
19 collecting sites and 9 geographical regions. They belong to the
following families: Scytodidae (1), Segestriidae (1), Dysderidae (8),
Nesticidae (1), Anapidae (1), Theridiidae (1), Linyphiidae (20),
Agelenidae (3), Cybaeidae (1), Dictynidae (2), Amaurobiidae (2),
Liocranidae (3), Corinnidae (1), Zodariidae (1), Gnaphosidae (5), and
Salticidae (1). The family Anapidae, with the species Zangherella relicta
(Kratochvíl, 1935) is recorded from three sites in the Pirin and Slavyanka
mountains, and this represents the first record of the family, genus and
species in Bulgaria. In spite of the active investigations of the epigean
and cave spiders in these regions over the years Z. relicta was not found
and it seems it occurs only in deeper subterranean habitats and nowhere
else. Comparative study of almost topotypic specimens of Z. relicta from
Montenegro with those collected from Bulgaria showed no variation in
the shape of palp and female vulvae. Until the true identity of Z. apuliae
(Caporiacco, 1949) from Italy is revealed, it remains unclear whether Z.
relicta and Z. apuliae are conspecific, as it remains unclear whether the
older records of Z. apuliae from the Balkan Peninsula refer to this species
or to Z. relicta. Pelecopsis mengei (Simon, 1884) (Linyphiidae) and
Scotolathys simplex Simon, 1884 (Dictynidae) are also reported from
Bulgaria for the first time, the latter being also new to FYR of
Macedonia. A faunistic overview of the spiders found in these
underground environments is made, along with remarks on the
distribution and ecology of some rare and interesting species. The
presence of cave-dwelling and superficial spiders in the sampled sites
indicates that SUC and euedaphon are inhabited by different ecotypes, e.
g. litter- (tanathostromic), soil- (edaphic) and cave- (troglobitic) which at

for centuries, and clades consisting primarily of cave-adapted species are
even more intriguing. The percopsiforms are an enigmatic group of fishes
comprised of nine species in seven genera, with four species in three
genera exhibiting characteristic troglomorphic features, such as a lack of
pigmentation and eyes. Nucleotide characters presented here provide the
first test of monophyly for both the Percopsiformes and Amblyopsidae
with this character type and taxonomic completeness. Characters of ND2
support a monophyletic Percopsiformes and Amblyopsidae and further
document phylogeographic subdivision in two stygobitic genera,
Amblyopsis and Typhlichthys, in Amblyopsidae. Age estimates from
time-calibrated branch lengths utilizing two independent intra-lineage
fossils indicate that the ancestor to amblyopsids is Eocene in age, and that
phylogeographic subdivision in both Amblyopsis and Typhlichthys
occurred primarily in the Miocene. Interestingly, ancestral character state
reconstruction for the amblyopsids strongly supports the re-evolution of
eyes and body pigment. While certainly unconventional, but supported
with this character set, the hypothesis provides continued challenge to
Dollo's Law.

We examined the biodiversity of cave animals on the campus at the
species level and at the genetic level. Through a survey of seven caves on
the campus, we identified 24 cave-obligate species, including two new
county records. This total accounts for half of the cave-obligate species
reported for Franklin County. For our genetic analysis, we selected six
diverse taxa (two millipedes, a beetle, a fly, an aquatic isopod, and a
spider) that were collected from multiple caves, and compared their
mitochondrial cytochrome oxidase I gene sequences. Across the six taxa
we found: (1) low genetic diversity within caves (mean nucleotide
diversity within caves across all taxa: 0.25%), (2) high genetic divergence
between caves (divergence between caves within taxa ranged from 2.5%10.9%, with two exceptions), and (3) little evidence for gene flow
between caves (FST between caves within taxa >0.57, with one
exception). Thus, the campus supports tremendous species diversity, and
even more remarkable genetic diversity within those species on a small
geographic scale (no studied caves were >7 km apart). The divergence
between cave populations and lack of gene flow between them that we
observed across a range of taxa highlight the importance of cave
conservation on a regional scale.

DOI:
http://dx.doi.org/10.4311/jcks2010lsc0145. ABS: Small caves
provide habitat for a variety of species, including bats. Past research on
cave bats in Iowa has focused on a few large caves. Large caves are
uncommon and represent only a portion of the known caves in the state.
Since few hibernacula are protected in Iowa and no assessment of small
caves has been done, bat census data were compared to cave morphology
to determine the significance of small caves as hibernacula. Twelve years
of census data (1998-2009) were reviewed for small caves (≤50.0 m in
length) where hibernating bats had been documented. Four morphological
features were compared against the data: entrance aspect, entrance size,
cave length, and internal surface area. Student's t-test and Spearman rank
correlation were used to test for relationships between the presence and
abundance of each species and each of the four morphological features.
The eastern pipistrelle occurred in 68% of the caves, and the little brown
bat in 24%. Student's t-test showed a significant correlation with cave
length for eastern pipistrelles. Spearman rank correlation showed a
significant negative correlation with entrance aspect and significant
positive correlations for cave length and internal surface area for eastern
pipistrelles. The results are different from previous studies on larger Iowa
caves, which showed big brown bats and little brown bats as the most
abundant species. Eastern pipistrelles preferred larger caves with vertical
entrances. However, large is a subjective term, and the results indicate
that small caves are an important source of hibernacula for the eastern
pipistrelle.

this work, we study the spore content of the atmosphere of the Cave of
Nerja, a karstic cavity and an important tourist attraction situated on the
eastern coast of Malaga (southern Spain), which receives more than half a
million visitors every year. This study was carried out over an
uninterrupted period of 4 years (2002-2005) with the aid of two Hirsttype volumetric pollen traps (Lanzoni VPPS 2000) situated in different
halls of the cave. In the atmosphere of the Cave of Nerja, 72 different
spore types were detected during the studied period and daily mean
concentrations of up to 282,195 spores/m3 were reached. Thirty-five of
the spore types detected are included within Ascomycota and
Basidiomycota (19 and 16 types, respectively). Of the remaining spore
types, 32 were categorized within the group of so-called imperfect fungi,
while Oomycota and Myxomycota were represented by 2 and 3 spore
types, respectively. Aspergillus/Penicillium was the most abundant spore
type with a yearly mean percentage that represented 50% of the total,
followed by Cladosporium. Finally, the origin of the fungal spores found
inside the cave is discussed on the basis of the indoor/outdoor
concentrations and the seasonal behaviour observed. Research Highlights:
Fungal spores are of great interest due to their high presence in the air. A
four-year study was carried out inside a natural cave (Cave of Nerja,
Spain). 72 spore types were detected, Aspergillus/Penicillium being the
most abundant (50%). The origin of fungal spores was analysed by
indoor/outdoor comparative studies. Most spores, excluding
Aspergillus/Penicillium, could come from outside. KW: Aerobiology,

adult individuals inhabiting almost exclusively the Limanu cave. In the
present study, we investigated the genetic consequences of population
decline for the viability of the remaining population of R. mehelyi in
Romania. We sequenced and analyzed a 359-bp fragment of the
mitochondrial control region from the only known Romanian population

DOI:
http://dx.doi.org/10.1016/j.cub.2011.03.020. SUM: Patterns of
sleep vary widely among species [[1], [2], [3] and [4]], but the functional
and evolutionary principles responsible for this diversity remain
unknown. The characin fish, Astyanax mexicanus, has eyed surface and
numerous blind cave populations [5]. The cave populations are largely
independent in their origins, and the species is ideal for studying the
genetic bases of convergent evolution [[5], [6] and [7]]. Here we show
that this system is also uniquely valuable for the investigation of
variability in patterns of sleep. We find that a clearly defined change in
ecological conditions, from surface to cave, is correlated with a dramatic
reduction in sleep in three independently derived cave populations of A.
mexicanus. Analyses of surface × cave hybrids show that the alleles for
reduced sleep in the Pachón and Tinaja cave populations are dominant in
effect to the surface alleles. Genetic analysis of hybrids between surface
and Pachón cavefish suggests that only a small number of loci with
dominant effects are involved. Our results demonstrate that sleep is an
evolutionarily labile phenotype, highly responsive to changes in
ecological conditions. To our knowledge, this is the first example of a
single species with a convergence on sleep loss exhibited by several
independently evolved populations correlated with population-specific
ecologies. Highlights: Blind Mexican Cavefish sleep much less than
conspecific surface fish. Three cave populations converged independently
on a sleep loss phenotype. Sleep phenotype in this species correlates with
population-specific ecology.

DOI: http://dx.doi.org/10.1643/CG-10-075. ABS: The
subgenus Nenirana of North American ranid frogs encompasses Pickerel
Frogs (Lithobates palustris), Crawfish Frogs (L. areolatus), Gopher Frogs
(L. capito), and Dusky Gopher Frogs (L. sevosus). All four species
inhabit caves, crevices, stump holes, and/or burrows when not in breeding
wetlands. Crawfish Frogs obligately inhabit crayfish burrows as their
primary retreat sites, and in this study we examine whether the deep,
small-bore crayfish burrows used by Crawfish Frogs have influenced
Crawfish Frog morphology. Specimens of all four species of Nenirana
were radiographed and snout-urostyle length, maximum headwidth, head
length, femur length, and tibiofibula length were measured from films.
Our results suggest that if Crawfish Frog morphology is a response to life
in burrows, it is due in part to having the size characteristic of being the
largest member of the clade and in part through the shape characteristic of
generally exhibiting an intermediate morphology between Pickerel Frogs
and the two Gopher Frog species. Not all shape metrics, however, are
intermediate; among Nenirana, Crawfish Frogs have the longest
hindlimbs and the relatively bluntest snouts. Further, Crawfish Frogs
exhibit positive allometry in headwidth, a reversal of the ancestral pattern
exhibited by Pickerel Frogs. None of the morphological features of
Crawfish

fit
neatly
into
known
or
predicted
functional/morphological cause-and-effect relationships associated with
burrow occupancy. It may be that the ranid body plan is generalized
enough to permit Crawfish Frogs to inhabit, despite being unable to dig,
deep small-bore burrows without undergoing major morphological
changes.

surfaces, with Gammaproteobacteria and Epsilonproteobacteria

with respect to calcite, experimental calcite from in situ microcosms had
significantly greater mass loss when colonized. Moreover, neoformed
gypsum crystals were observed on colonized surfaces where fluids were
undersaturated with respect to gypsum. The results are similar to findings
from shallow cave and karst environments, and highlight the

(Coleoptera) are one of the main groups of insects that colonized the
subterranean environment. Many species of this group have developed
similar morphological modifications related to the subterranean life,
resulting in a characteristic Aphaenops-like phenotype that obscures their
phylogenetic relationships (depigmented, blind, elongated body and
appendages, narrow head and pronotum). We present here the result of a
molecular study using a combination of nuclear (small ribosomal unit,
large ribosomal unit) and mitochondrial (cox1, cyb, rrnL, trnL, nad1)
genes to investigate the phylogenetic placement of the highly modified
subterranean genera of the tribe Trechini from the west Mediterranean
area (France, Spain, Morocco and Sardinia). Our results confirm the
multiple independent origin of troglomorphism among these genera, and
reveal a pattern largely determined by geographical proximity. We
discuss the validity of some groups proposed on the base of
morphological features, and provide estimates of divergence between
subterranean genera and other groups of Trechini, including epigean
species of the same area. We compare the estimated age for the origin of
the main groups resulting from two different calibrations, using one the
standard mitochondrial mutation rate (2.3% divergence per Myr) and the
other the separation between Sardinia and mainland 33 Ma. Under the
first scenario, the main groups of genera would have a late Miocene
origin, with a subsequent colonization of north Africa at the PliocenePleistocene boundary. The assumption that the main groups originated
through vicariance due to the separation of the Sardinian plate in the
Oligocene results in a Messinian origin of the north African subterranean
taxa, and a global mitochondrial rate reduced to 1% divergence per Myr.

spacer 1 ribosomal DNA region (ITS-1) was amplified from specimens of
P. juanibali and P. saenzi, and from specimens of Pseudocyclops that
were morphologically identical to P. juanibali but from two different
anchialine pools. The phylogenetic analysis of the ITS-1 region shows
that P. juanibali and P. saenzi are genetically different from each other
and, furthermore, that the specimens from the two other anchialine pools
are genetically isolated from the former species, a finding that suggests
cryptic speciation. The morphological and genetic evidence presented
here, including confirmation of a close sibling species of P. juanibali
from the Ryukyu Islands of Japan, demonstrate that vicariance and active
migration are responsible for the observed distribution of species, with
faunal exchange occurring between the Galapagos and the Caribbean and
Western Pacific Oceans. However, although these copepods are able to
cross the entire Pacific, such long-range migration is not the norm. They
tend to have restricted distributions with minimal migration and gene
exchange, even between habitats that are very close to each other such as
the anchialine pools in the Galapagos. KW: Anchialine pools, Copepoda,

Thornton's Cave, an Estavelle in west-central Florida, SEM, EDS, and

Fragments of this crystalline biofilm adhere to the walls and ceiling as
water levels vary within the cave. Those on the wall have a "cornflake"
appearance and those affixed to the ceiling hang as fibrous membranes.
PCR of DNA in the active biofilm, combined with morphologic data from
the tubes in SEM micrographs, point to Leptothrix sp., a common Feoxidizing bacteria, as the primary organism in the biofilm. Recent
discoveries of "rusticles" in other Florida caves suggest that Fe-oxidizing
bacteria may reside elsewhere in Florida groundwater and may play a role
in the mobility of trace metals in the Upper Florida aquifer. SEM
micrographs from two marble tablets submerged for five months, one
exposed to microbial activity and a second isolated from microbial action,
revealed no visible etchings or borings and very limited loss of mass.
EDS data from the electron micrographs of the unfiltered tablet document
the same FeOOH-encrusted hollow sheaths and similar deposits of calcite
as seen in the "cornflakes". These results, combined with water chemistry
data imply that the biofilm may focus or even promote calcite
precipitation during low-water level conditions when CO2 degasses from
the cave pools. KW: Scanning electron microscopy, x-ray diffraction,

Between 1986 and 2009 nine submersible and remote-operated vehicle
expeditions were carried out to study the population biology of the
coelacanth Latimeria chalumnae in the Comoro Islands, located in the
western Indian Ocean. Latimeria live in large overlapping home ranges
that can be occupied for as long as 21 years. Most individuals are
confined to relatively small home ranges, resting in the same caves during
the day. One hundred and forty five coelacanths are individually known,
and we estimate the total population size of Grande Comore as
approximately 300-400 adult individuals. The local population inhabiting
a census area along an 8-km section of coastline remained stable for at
least 18 years. Using LASER-assisted observations, we recorded length
frequencies between 100 and 200 cm total length and did not encounter
smaller-bodied individuals (<100 cm total length). It appears that
coelacanth recruitment in the observation areas occur mainly by
immigrating adults. We estimate that the mean numbers of deaths and
newcomers are 3-4 individuals per year, suggesting that longevity may
exceed 100 years. The domestic fishery represents a threat to the longterm survival of coelacanths in the study area. Recent changes in the local
fishery include a decrease in the abundance of the un-motorized canoes
associated with exploitation of coelacanths and an increase in motorized

Underground environments are increasingly recognized as reservoirs of
faunal diversity. Extreme environmental conditions and limited dispersal
ability of underground organisms have been acknowledged as important
factors promoting divergence between species and conspecific
populations. However, in many instances, there is no correlation between
genetic divergence and morphological differentiation. Lucifuga Poey is a
stygobiotic fish genus that lives in Cuban and Bahamian caves. In Cuba,
it offers a unique opportunity to study the influence of habitat
fragmentation on the genetic divergence of stygobiotic species and
populations. The genus includes four species and one morphological
variant that have contrasting geographical distributions. In this study, we
first performed a molecular phylogenetic analysis of the Lucifuga Cuban
species using mitochondrial and nuclear markers. The mitochondrial
phylogeny revealed three deeply divergent clades that were supported by
nuclear and morphological characters. Within two of these main clades,
we identified five lineages that are candidate cryptic species and a
taxonomical synonymy between Lucifuga subterranea and Lucifuga
teresinarum. Secondly, phylogeographic analysis using a fragment of the
cytochrome b gene was performed for Lucifuga dentata, the most widely

distributed species. We found strong geographical organization of the
haplotype clades at different geographic scales that can be explained by
episodes of dispersal and population expansion followed by population
fragmentation and restricted gene flow. At a larger temporal scale, these
processes could also explain the diversification and the distribution of the
different species. Highlights: mtDNA phylogeny of the Cuban cave fishes
(Lucifuga) revealed three main clades. Nuclear and morphological
characters support these clades. Five putative new cryptic species were
identified within two of these clades. Phylogeography indicates that
dispersal and vicariance have moulds this diversity. The evolutionary
trends of four phenotypic traits were inferred. KW: Blind cave fish,

cavernicola di Creta [A new cave-dwelling Harpactea
from Crete (Araneae, Dysderidae)]. Atti e Memorie della
Commissione Grotte "Eugenio Boegan" 43:57-65. RIAS:
Viene descritta Harpactea persephone n. sp. su di un singolo esemplare
di sesso femminile, recentemente rinvenuto nella grotta di Kournas
(Spilaio tou Kourna), presso il villaggio omonimo (prefettura di Chania,
Creta). La nuova specie, di grande taglia e caratterizzata da un'accentuata
riduzione e depigmentazione oculare, si distingue da tutte le specie
conosciute del genere Harpactea per la spinulazione straordinariamente
abbondante delle zampe, con spine presenti su tutti i segmenti, eccezion
fatta per le coxe e le patelle anteriori e tutti i tarsi; in particolare un
numero inconsueto di spine (circa 10) si riscontra sulle tibie ed i metatarsi
del primo e secondo paio di zampe. Harpactea persephone n. sp.
appartiene al gruppo rubicunda e, in base alla struttura della vulva,
presenta evidenti affinità con H. catholica (Brignoli, 1984), specie
troglofila raccolta anche in sede epigea, endemica del settore occidentale
di Creta. SUM: Harpactea persephone n. sp. is described on a single
female specimen collected in the Kournas cave (Spilaio tou Kourna),
Chania prefecture, Crete. The main diagnostic characters of the new
species are: the large body size, a strong eye reduction and
depigmentation and the very abundant leg spination: spines are present on
all leg segments, except for the anterior coxae and patellae and all the
tarsi; an absolutely high number of spines (about 10 on each segment) are
located on the tibiae and metatarsi of the first and second pair of legs.
Due to the above features, the new species is easily distinguished from all
the congeners. Harpactea persephone n. sp. belongs to the rubicunda
group and, according to the vulvar structure, appears to be related to H.
catholica (Brignoli, 1984), a troglophilic species (often found outside

sheath-tailed bat Coleura seychellensis from 1997-2011

Endangered Seychelles sheath-tailed bat Coleura seychellensis has been
the subject of conservation activity on Silhouette Island since 1997, in
addition research into its status has been carried out on Mahé island. The
species was more abundant in the past and many known roosts have been
abandoned. The causes of decline have been speculated to include
disturbance and predation but studies of the roosts suggest that habitat
change may be the most significant factor. The species occupies small
caves in boulder fields in lowland woodland which has been extensively
invaded by introduced plants. These plants support reduced numbers of
insects, especially Coleoptera. Lepidoptera and Coleoptera dominate the
diet with a strong preference for the latter before and during the breeding
season. Habitat management on Silhouette has removed alien plants from
around the roosts and improved foraging conditions for the bat resulting
in an increase in breeding activity. The population at La Passe on
Silhouette has increased from 14-25 individuals in the 1990s to 40 in
2009. In 2010 this colony fragmented with 18-20 individuals leaving to
start a second colony at Anse Lascars. The forced closure of the
conservation project in March 2011 means that all conservation action for
the species has ceased. In the absence of Seychelles government

Intraspecific variation in eye size in relation to ecological factors has not
been well studied. Here, for the first time, we show that larger eyes in a
freshwater crustacean may be associated with the presence of predators.
In central Pennsylvania (USA), individuals of the amphipod crustacean
Gammarus minus have significantly larger eyes in two freshwater springs
with numerous fish predators (Cottus cognatus) than in three springs with
few or no fish predators. Although we do not know the precise causes of
these differences, this study and previous work on cave populations of G.
minus suggest that eye size is an evolutionarily malleable trait that may
respond to multiple selection pressures, either directly or indirectly. Three
plausible explanations for the eye-size variation observed among our
study populations include (1) larger eyes may enable amphipods to better
detect and avoid fish predators, (2) fish predation favors nocturnal or
shallow interstitial activity that is facilitated by larger, more lightsensitive eyes, or (3) the presence of fishes is associated with other

environmental factors that may favor relatively large eyes. Available
evidence suggests that the first hypothesis is the most viable explanation,

http://dx.doi.org/10.3390/insects2030369. ABS: A prediction
in phylogeographic studies is that patterns of lineage diversity and timing
will be similar within the same landscape under the assumption that these
lineages have responded to past environmental changes in comparable
ways. Eight invertebrate taxa from four different orders were included in
this study of mainland New Zealand and Chatham Islands lineages to
explore outcomes of island colonization. These comprised two
orthopteran genera, one an endemic forest-dwelling genus of cave weta
(Rhaphidophoridae, Talitropsis) and the other a grasshopper (Acrididae,
Phaulacridum) that inhabits open grassland; four genera of Coleoptera
including carabid beetles (Mecodema), stag beetles (Geodorcus), weevils
(Hadramphus) and clickbeetles (Amychus); the widespread earwig genus
Anisolabis (Dermaptera) that is common on beaches in New Zealand and
the Chatham Islands, and an endemic and widespread cockroach genus
Celatoblatta (Blattodea). Mitochondrial DNA data were used to
reconstruct phylogeographic hypotheses to compare among these taxa.
Strikingly, despite a maximum age of the Chathams of ~4 million years
there is no concordance among these taxa, in the extent of genetic
divergence and partitioning between Chatham and Mainland populations.
Some Chatham lineages are represented by insular endemics and others
by haplotypes shared with mainland populations. These diverse patterns
suggest that combinations of intrinsic (taxon ecology) and extrinsic
(extinction and dispersal) factors can result in apparently very different
biogeographic outcomes. KW: New Zealand, Chatham Islands, insects,

metacommunities can be separated into 3 main components: size (i. e.,
number of habitat patches), spatial arrangement of habitat patches
(network topology), and diversity of habitat patch types. Much attention
has been paid to lattice-type networks, such as patch-based
metapopulations, but interest in understanding ecological networks of
alternative geometries is building. Dendritic ecological networks (DENs)
include some increasingly threatened ecological systems, such as caves
and streams. The restrictive architecture of dendritic ecological networks

might have overriding implications for species persistence. I used a
modeling approach to investigate how number and spatial arrangement of
habitat patches influence metapopulation extinction risk in 2 DENs of
different size and topology. Metapopulation persistence was higher in
larger networks, but this relationship was mediated by network topology
and the dispersal pathways used to navigate the network. Larger
networks, especially those with greater topological complexity, generally
had lower extinction risk than smaller and less-complex networks, but
dispersal bias and magnitude affected the shape of this relationship.
Applying these general results to real systems will require empirical data
on the movement behavior of organisms and will improve our
understanding of the implications of network complexity on population
and community patterns and processes. KW: Dendritic ecological

various atmospheric environments. Aerobiologia 27(1,
March):25-35. DOI: http://dx.doi.org/10.1007/s10453-0109173-z. ABS: The influence of sample-collection-time on the recovery
of culturable airborne microorganisms using a low-flow-rate membranefiltration unit and a high-flow-rate liquid impinger were investigated.
Differences in recoveries were investigated in four different atmospheric
environments, one mid-oceanic at an altitude of ~10.0 m, one on a
mountain top at an altitude of ~3,000.0 m, one at ~1.0 m altitude in
Tallahassee, Florida, and one at ~1.0 m above ground in a subterraneancave. Regarding use of membrane filtration, a common trend was
observed: the shorter the collection period, the higher the recovery of
culturable bacteria and fungi. These data also demonstrated that lower
culturable counts were common in the more remote mid-oceanic and
mountain-top atmospheric environments with bacteria, fungi, and total
numbers averaging (by sample time or method categories) <3.0 colonyforming units (CFU) m-3. At the Florida and subterranean sites, the lowest
average count noted was 3.5 bacteria CFU m-3, and the highest averaged
140.4 total CFU m-3. When atmospheric temperature allowed use, the
high-volume liquid impinger utilized in this study resulted in much higher
recoveries, as much as 10 × greater in a number of the categories
(bacterial, fungal, and total CFU). Together, these data illustrated that (1)
the high-volume liquid impinger is clearly superior to membrane
filtration for aeromicrobiology studies if start-up costs are not an issue
and temperature permits use; (2) although membrane filtration is more
cost friendly and has a "typically" wider operational range, its limits

current diagnostic characters has likely resulted in misidentifications. To
address this issue, we carried out molecular-phylogenetic analyses of
Cytochrome Oxidase Subunit 1 gene (COI) and 28S rDNA sequences for
34 individuals of the three species from 27 sites in Central Europe and
Great Britain. We also included 14 GenBank sequences for two
additional species, N. virei and N. rhenorhodanensis, to increase the
resolution potential among our in-group taxa. In addition, about 100
specimens of the three species were examined for a reappraisal of
diagnostic characters. Representative specimens taken from various
subterranean habitat types were examined for each of the three species. A
new morphological key, utilizing improved characters, is presented to
clearly distinguish between N. fontanus, N. aquilex, and N. schellenbergi.
Molecular-phylogenetic analysis using COI sequence data indicates
geographically well-delimited clades for N. aquilex and N. fontanus. Our

Astyanax has become an important model system for evolutionary studies
of cave animals. We investigated correlations of population genetic
patterns revealed by microsatellite data and phylogeographic patterns
shown by mitochondrial DNA sequences in Mexican cave and surface
fish of the genus Astyanax (Characidae, Teleostei) to improve the
understanding of the colonization history of this neotropical fish in
Central and North America and to assess a recent taxonomic
classification. The distribution of nuclear genotypes is not congruent with
that of the mitochondrial clades. Admixture analyses suggest there has
been nuclear gene flow between populations defined by different
mitochondrial clades. The microsatellite data indicate that there was
mitochondrial capture of a cave population from adjacent populations.
Furthermore, gene flow also occurred between populations belonging to
different nuclear genotypic clusters. This indicates that neither the nuclear
genotypic clusters nor the mitochondrial clades represent independent
evolutionary units, although the mitochondrial divergences are high and
in a range usually characteristic for different fish species. This conclusion
is supported by the presence of morphologically intermediate forms. Our
analyses show that the Trans-Mexican Volcanic Belt limited gene flow,

but has been crossed by Astyanax several times. In Yucatán, where
obvious geographic barriers are missing, the incongruence between the
distribution of nuclear and mitochondrial markers reflects random
colonization events caused by inundations or marine transgressions
resulting in random phylogeographic breaks. Thus, conclusions about the
phylogeographic history and even more about the delimitation of species
should not be based on single genetic markers. Highlights: Incongruence
between nuclear genotypic clusters and mitochondrial clades. Gene flow
between groups with different mitochondrial clades. Mitochondrial
capture of a cave population. The Trans-Mexican Volcanic Belt is not a
complete geographic boundary for Astyanax. Random phylogeographic

describe four new species of cochliopid snails from thermal springs in
northeastern Mexico (Chihuahua, Coahuila and Durango States). Two of
these are placed in Pseudotryonia and represent the first Mexican records
for this genus. They are diagnosed by unique or unique combinations of
shell and anatomical characters, are well differentiated genetically from
both each other and other congeners (mtCOI sequence divergence ≥2.0%)
and were resolved as sister species within the Pseudotryonia clade in our
molecular phylogenetic analyses. The other two species resemble
Ipnobius, Pseudotryonia and Tryonia in having a thin, narrow shell, penis
ornamented with a small number of glandular papillae and ovoviviparous
reproductive mode, but are well differentiated (from these and each other)
by other morphological/anatomical characters and mtCOI sequences (8.612.5% and 5.2-12.1% divergence, respectively) and consequently are
placed in new monotypic genera (Chorrobius and Minckleyella).
Chorrobius and Minckleyella formed a clade with Ipnobius, Mexipyrgus
and Tryonia in all of our molecular phylogenetic analyses. Chorrobius
was consistently delineated as a divergent lineage within this clade, but
its relationships were otherwise unresolved. Minckleyella was nested
within Tryonia in most of the trees and was sister to this genus in the
others; despite this finding we erected a new genus for this snail because
of its highly distinctive anatomical features and large genetic divergence
relative to Tryonia (5.2 ± 0.6%). Each of the four new species is endemic
to highly disturbed single springs or local spring systems and may require
protection.

analysis of a mtCOI dataset resolved two clades composed of novelties
described herein: one (containing four species) is distributed in several
drainages in Chihuahua, the other (containing three species) is a local
species flock in the Río Conchos basin (also in Chihuahua) that lives in
the warmest waters yet recorded for Tryonia (41-44°C). (The
phylogenetic relationships of the other new species were not well
supported.) Both of these clades contain sympatric species pairs; cooccurrence of Tryonia congeners previously had been reported only in
Ash Meadows (southern Nevada). Some of the species described herein
are from previously unsurveyed localities and may help delineate new
areas of endemism within the Chihuahuan Desert. One of the new species
(T. julimesensis) became extinct between 1991 and 2001 and another (T.
oasiensis) disappeared from its single known locality shortly after it was
first discovered in 2009 and also may be extinct. The other species treated

of the two new Paracobanocythere species are the second and third for
this genus since the original description of P. hawaiiensis Gottwald,
1983. Cobanocythere ikeyai sp. nov., and C. lata sp. nov., from Japan are
morphologically more similar to the species of the "lanceolata group" by
Gottwald (1983) and C. guttaeformis Gottwald, 1983 from the Galapagos
Islands, respectively, rather than to other Cobanocythere species from
Japan. The Japanese archipelago (eastern Eurasian Continent) and the
Galapagos Islands (north-western South America) are separated by about
15000 km from each other, and have never been adjoined throughout
geological history. This fact, and also the morphological similarities
between Cobanocythere species from Japan and the Galapagos Islands,
suggests that this genus may have undergone global dispersal at several
times in the past. Conversely, the genera Cobanocythere and
Paracobanocythere are distributed not only around continents and
continental islands but also around oceanic islands such as the Hawaiian
and Galapagos Islands. We conclude, therefore, that the cobanocytherids
seem to have been able to disperse long distances across oceans. KW:

demonstrate an independent clade as belonging to only one type. The L

they express an intra-sexual dimorphism. We also argue that the
morphological features of the male copulatory organ could have changed
prior to the establishment of reproductive isolation. KW: COI, Intrasexual dimorphism, male copulatory organ, Microloxoconcha dimorpha,

DOI:
http://dx.doi.org/10.1073/pnas.1104636108. ABS: Current
theory predicts that a shift to a new habitat would increase the rate of
diversification, while as lineages evolve into multiple species, intensified
competition would decrease the rate of diversification. We used Holarctic
amphipods of the genus Gammarus to test this hypothesis. We sequenced
four genes (5088 bp) for 289 samples representing 115 Gammarus
species. A phylogenetic analysis showed that Gammarus originated from
the Tethyan region with a saline ancestry in the Paleocene, and later
colonized the freshwater habitat in the Middle Eocene. Ancestral range
reconstruction and diversification mode analysis combined with
paleogeological and paleoclimatic evidence suggested that the habitat
shift from saline to freshwater led to an increased diversification rate. The
saline lineage of Gammarus dispersed to both sides of the Atlantic at 55
million years ago (Ma), because of the few barriers between the Tethys
and the Atlantic, and diversified throughout its evolutionary history with
a constant diversification rate [0.04 species per million years (sp/My)].
The freshwater Gammarus, however, underwent a rapid diversification
phase (0.11 sp/My) until the Middle Miocene, and lineages successively
diversified across Eurasia via vicariance process likely driven by changes
of the Tethys and landmass. In particular, the freshwater Gammarus
lacustris and Gammarus balcanicus lineages had a relatively high
diversification shift, corresponding to the regression of the Paratethys Sea
and the continentalization of Eurasian lands during the Miocene period.
Subsequently (14 Ma), the diversification rate of the freshwater
Gammarus decreased to 0.05 and again to 0.01 sp/My. The genus
Gammarus provides an excellent aquatic case supporting the hypothesis
that ecological opportunities promote diversification. KW: Evolution,

The final instar larva of Bbo. hoplocephalus was unusual in its globose

presented which suggests that females of at least Bbu. reichei (and
probably other species) deposit their eggs in comparatively small, bare,

(e. g., plant litter vs carrion). Variability in detrital quantity and quality
potentially affects consumer biomass and rates of organic matter (OM)
breakdown. We used cave streams to test 2 linked hypotheses regarding
the influence of total detrital inputs on consumer biomass and the
breakdown of high-quality carrion detritus. First, we hypothesized that
cave systems with higher total OM availability would support a higher
biomass of consumers. Second, we predicted that higher consumer
biomass would cause faster carrion breakdown rates. To test these
hypotheses, we quantified macroinvertebrate biomass and breakdown
rates (k, d-1) of carrion (mouse carcasses, Mus musculus) in 4 cave
streams in northeastern Alabama and southeastern Tennessee (USA) that
varied in total OM storage. We estimated carrion breakdown rates in
coarse- and fine-mesh packs (10-mm and 500-µm mesh size) to isolate
the influence of scavenging by crayfish. Macroinvertebrate biomass
(excluding crayfish) in carrion packs was positively correlated with OM
storage, but neither macroinvertebrate biomass (excluding crayfish) nor
OM storage were strong predictors of carrion breakdown rates. Crayfish
biomass was not correlated with total OM storage but was positively
correlated with coarse-mesh breakdown rates. Our study illustrates the
influence of community structure and consumer biomass on detrital
breakdown rates in cave ecosystems. However, determining how detrital
inputs structure cave communities will require further study. KW:

SUM: 1. Surface ecosystems provide the primary source of organic
matter to many cave communities. Variation in the strength of
connectivity to the surface suggests that some caves may be more
resource-limited than others. To test this, we examined diet, prey
availability and production of an obligate cave salamander Gyrinophilus
palleucus (Plethodontidae), a top predator, in two south-eastern U. S. A.
caves with different levels of organic matter (Tony Sinks cave, 165 g
AFDM m-2; Bluff River cave, 62 g AFDM m-2). 2. We quantified density,
biomass, growth rate, production and diet of G. palleucus monthly for 21
months. Diet composition, differences in prey communities and seasonal
patterns in prey consumption were also analysed. 3. Salamander density,
biomass and secondary production were significantly greater in the high
organic matter cave (0.10 m-2, 0.18 g AFDM m-2, 0.12 g AFDM m-2 year1
) than in the low organic matter cave (0.03 m-2, 0.03 g AFDM m-2, 0.01 g
AFDM m-2 year-1). Although growth rates were not statistically different
between the two cave salamander populations, low recaptures probably
influenced this result. 4. Isopoda prey were the major contributor to
salamander production in the high organic matter cave (69%). In the low
organic matter cave, production was provided by isopods (41%) and
oligochaetes (20%). The lower number of prey taxa contributing to

salamander production in the high organic matter cave suggests the
ability to forage more selectively. 5. The differences in foraging strategy,
density, biomass and secondary production were probably related to
differences in the strength of surface connectivity, which controls organic
matter supply. Links between basal resource level and top predator
performance show the importance of bottom-up limitation in the food
webs of caves and other detritus-based ecosystems. KW: Bottom-up

Subterranean ecosystems often harbour unique and specialised
biocoenoses of considerable scientific interest and high potential
conservation value. In view of the peculiar species assemblage in the
abandoned tunnels of a talc mine complex in the north-western Italian
Alps (Germanasca Valley, Province of Turin, NW Italy), the aims of the
present work were (i) to investigate the subterranean invertebrate fauna,
(ii) to assess the impact of tourism activities on the invertebrate fauna,
and (iii) to assess the conservation value of the terrestrial invertebrate
community and associated habitats. The study was carried out at four
sites: one tunnel restored for tourism purposes; two abandoned tunnels;
and a wild cave. The results of several statistical analyses, including
ANOVA, PCA and CCA, showed that the eutrophic conditions induced
by past human activity could improve the quality of the subterranean
habitat. On the other hand, a massive intervention for tourism purposes
could seriously jeopardise the survival of the most sensitive species. The
increased thermic instability and mean temperature had a significant
negative effect on the local populations of cave-dwelling arthropods,
whose ecological optimum is determined primarily by low thermic
instability, cold temperatures and intermediate conditions of eutrophy. On
the basis of our results we strongly recommend to avoid thermic isolation
of any part of tunnels, as it is the primary factor affecting the most
sensitive species. KW: Cave-dwelling arthropods, CCA, Eutrophy,

Growth lines evident in cross sections through stalactites from Nani Cave
provide a temporal record of their growth. Many of these dark, organicrich laminae developed as biofilms that are recognized by the presence of
(1) a diverse microbial biota that is dominated by actinomycetes, (2)
calcified filaments, (3) films formed of extracellular polymeric
substances (EPS), (4) grain-coating sheets of calcite crystals that grew in
EPS, (5) biterminal calcite crystals, and (6) etching. This biosignatures
suite encompasses a variety of constructive and destructive processes.
Where fully developed, the features generated by the biofilms form a
distinctive microstratigraphic succession, collectively <50 µm thick,
which can be traced laterally across the stalactite's surface. The use of
speleothems in paleoclimate studies is commonly framed against a
chronology that relies, at least in part, on annual growth couplets. The
dark, organic-rich lamina that forms one part of the growth couplet is
typically ascribed to abiotic precipitation that incorporated exogenic
organic matter that was flushed into the cave following the first major
rainfall of the wet season. This assumption ignores the possibility that

dark, organic-rich growth laminae can be the record of biofilms that
developed on the surface of the stalactites and hence, may not be a record
of annual events.

comprise 12 currently known species and phylogenetic lineages. On the
basis of the results of previous molecular studies and the extensive
morphometric analysis, appropriateness of several former and the
existence of some new metric descriptors are examined by multivariate
statistical methods. In discriminant function analyses (DFA), all
subgenera are distinctly separated even when only sexually nondimorphic characters are used. Since considerable number of these
characters is acknowledged, a joined analysis of both sexes is proven to
be appropriate for the identification of the subgenera. Characters for the
species recognition of Spelaeocaris and Troglocaridella females are
provided. In the subgenus Troglocaris s. str., molecularly recognized
phylogroups are separated by DFA despite the expressed clinal variation.
Also, minimum spanning tree (MST) demonstrates the existence of
considerable morphological differences. The amounts of morphological
difference (indicated by the length of the MST lines) and genetic
difference are concordant i. e. morphological differences among the
subgenera exceed the ones within the subgenera. KW: Morphometry,

material of already described species deposited in various museums. The
following two new genera are proposed: Kempfcyclocypris gen. nov. and
Keysercypria gen. nov. The genus Kempfcyclocypris is erected to include
single new species from subterranean waters of New South Wales,
Australia. Kempfcyclocypris australis gen. et sp. nov. can be
distinguished from other members of the subfamily by the following
characters: 6-segmented antennula, absence of the sexual bristles on
antenna, weakly asymmetrical prehensile palps, absence of the basal seta
on the second thoracopod, and the long distal seta on the penultimate
segment of the third thoracopod. Keysercypria is erected to include some
South American species previously described in the genera Physocypria
Vávra, 1897 or Cypria Zenker, 1854. The main characters of this genus
are: rather globular carapace, with or without marginal tubercles; very
short setae on endopodal segments of the third thoracopod; unequally
long setae "h1" and "h2" on the terminal segment of the same appendage;
and the presence of the basal seta on the second thoracopod. Keysercypria

range endemism in the Kinnecaris solitaria complex
(Copepoda: Parastenocarididae), with descriptions of
seven new species. Zootaxa 3026(September 14):1-64, 26
pl., 113 réf. ABS: Recent investigation of one of the larger calcretes in
the uppermost reaches of the Carey palaeochannel in the Yilgarn region
of Western Australia revealed an unprecedented diversity of copepod
crustaceans. Twenty-two different species and subspecies, from six
copepod families, represent 70% of the previously recorded copepod αdiversity in the whole region, although the area investigated is less than
3% of its surface. The aims of this study were to explore the diversity of
the harpacticoid genus Kinnecaris Jakobi, 1972 using both molecular and
morphological methods, establish precise species boundaries, find their
accurate area of distribution, reconstruct phylogenetic relationships, and
explore colonisation pathways. To achieve this we sampled very
intensively in the area, as well as in two neighbouring palaeochannels,
analysing more than 700 samples from 230 different localities, half of
which contained copepods. Seven species are described here as new, five
of them from the Yeelirrie palaeochannel (K. esbe sp. nov., K. lined sp.
nov., K. linel sp. nov., K. linesae sp. nov., and K. uranusi sp. nov.) and
one each from two neighbouring palaeochannels (K. barrambie sp. nov.
and K. lakewayi sp. nov.). Parastenocaris jane Karanovic, 2006 from the
Pilbara region, along with a newly described third Australian
parastenocaridid genus from the Yilgarn, were used as outgroups in our
molecular analysis. The COI fragment was successfully PCR-amplified
from 12 parastenocaridid specimens using a nested combination of
primers. All analyses supported the presence of at least seven genetically
divergent lineages, most supported with very high bootstrap values. Three
genera formed three separate clades, and the average pairwise distances
between Kinnecaris morpho-taxa were found to be very high (8.2-16.8
%), while the highest divergences within morpho-taxa were 0.3%. Some
conflict between molecular phylogenies and morphological data was
observed when it came to recognizing different groups of species. While
morphology indicates that K. esbe, K. linel, and K. uranusi represent a
group of very closely related species, supported by a number of
synapomorphies, molecular analyses suggest that K. linel and K. uranusi
are only remotely related. We argue in favor of morphological data, until
more markers can be studied to try to resolve these differences. In
Yeelirrie, morphological evidence would suggest a downstream
colonisation history in the genus Kinnecaris, where the most
plesiomorphic form (K. linesae) lives in the uppermost reaches of the
palaeochannel, and the trend in the caudal rami elongation and denser
somite ornamentation is obvious downstream the palaeochannel (K.
uranusi, K. linel, and then K. esbe), with the only exception being K.
lined, which probably represents an independent colonisation event.
Parastenocarids are copepods of freshwater origin, and we argure that
they can probably disperse downstream during periods of increased
rainfall, evolving into separate species in isolated calcrete pockets during
periods of increased aridity. Although some of the questions remained
unanswered in this study, detailed morphological and molecular
observations indicate that we are not dealing with one widely distributed
and variable species in the Yilgarn region, but rather with a complex of
short range endemics. Areas of distribution for different species range
from 30 km to less than 5 km in diameter. Very strong seasonal dynamics
in this subterranean community was observed, and this is a novel concept
for these ecosystems globally. A key to nine Australian species of
Kinnecaris is also included. KW: Western Australia, Harpacticoida,

new small subterranean cyclopid species are described from Australia in a
newly erected genus Anzcyclops n. gen.: A. yarriensis n. sp. (type), A.
belli n. sp., A. ballensis n. sp., and A. euryantennula n. sp. Three species
are from the Pilbara region in Western Australia, the fourth species from
central Queensland. Another previously described species from New
Zealand is transferred to this genus, A. silvestris (Harding, 1958) n.
comb., originally described in the genus Goniocyclops Kiefer, 1955. The
new genus has a number of unique features, including dorsoventrally
compressed habitus, reticulated integument of prosomites, and a
characterstic shape of the fifth leg. It is most closely related to the South
American genus Muscocyclops Kiefer, 1937, and the two share the same
spine formula of the swimming legs (2.3.3.2), but they can be
distinguished by a number of characters in the shape of the genital
double-somite, caudal rami, and anal operculum, as well as in the
armature of the first leg. Our preliminary cladistic analysis revealed the
polyphyletic nature of the endemic Australian genus Fierscyclops
Karanovic, 2004. As a result, the subgenus Pilbaracyclops Karanovic,
2006 is upgraded to full generic rank and its two species are given as new
combinations: P. supersensus (Karanovic, 2006) n. comb. (type) and P.
frustratio (Karanovic, 2006) n. comb. The assemblage of Australian
species previously considered members of the genus Metacyclops Kiefer,
1927 is also found to be polyphyletic and all five Australian
representatives and one New Zealand species of the so-called
"trispinosus"-goup are transferred into a newly erected genus
Pescecyclops n. gen.: P. laurentiisae (Karanovic, 2004) n. comb. (type),
P. pilanus (Karanovic, 2004) n. comb., P. arnaudi (G. O. Sars, 1908) n.
comb., P. monacanthus (Kiefer, 1928) n. comb., P. kimberleyi
(Karanovic, 2004) n. comb., and P. pilbaricus (Karanovic, 2004) n.
comb. After this, only two Australian species are left in the genus
Metacyclops: M. mortoni Pesce, De Laurentiis & Humphreys, 1996 and
M. superincidentis Karanovic, 2004. Pescecyclops is defined by the
presence of three spines on the distal exopodal segment of all swimming
legs, only one apical spine on the fourth leg endopod, and absence of any
sexual dimorphism in postantennular appendages, in addition to a
Metacyclops-like fifth leg. Two Australian species previously considered
members of Goniocyclops and one as a member of Allocyclops Kiefer,
1932 proved to be relatively closely related to each other and quite
separate from other members of their respective genera. They are
transferred into a third new genus, Dussartcyclops n. gen., although
subdivided into two subgenera: D. (s. str.) uniarticulatus (Karanovic,
2004) n. comb. (type), D. (s. str.) mortoni (Karanovic, 2004) n. comb.,
and D. (Barrowcyclops) consensus (Karanovic, 2003) n. comb. They all
have a reduced armature of the swimming legs (spine formula 2.2.2.2),
vermiform habitus, and the fifth leg exopod armed with two subequal
apical setae, but the subgenus Barrowcyclops n. subgen. has the exopod
of the fifth leg fused basally to the somite and the inner spine on the first
leg basis absent, in addition to a more plesiomorphic endopodal armature
of the first and fourth legs. RÉS: Quatre nouvelles espèces de petits

makes them valuable sites important for nature protection. Springs
located in the Krakow-Częstochowa Upland (southern Poland) are
characterized by low variability of environmental conditions, but their
benthic fauna composition is considerably different. Benthic
invertebrates, water chemistry as well as sediment characteristics of 25
springs were studied four times in 2003. The relationships between fauna
composition and abiotic parameters were ascertained using multivariate
statistical analyses. In total, fifty families or subfamilies and four higher
taxa of invertebrates were identified in the springs studied. Only
Gammarus fossarum (Amphipoda) occurred in all of the springs, whereas
crenophilic taxonomic groups such as Turbellaria, Bythinellinae,
Nemouridae, Limoniidae, Limnephilidae and Enchytraeidae as well as
ubiquitous taxa such as Tubificidae and Chironomidae were very
common but not present in all springs. Important factors determining
differences in the taxonomic composition (at the family level) of the
invertebrate fauna of springs were found to be those connected with their
geographical location as well as chemical and discharge parameters,
which were different for southern and northern groups of springs. The
taxonomic richness, i. e. the number of invertebrate taxa, was found to be
strongly dependent on discharge and the content of organic matter in
bottom sediments, whereas specific taxa mentioned above had other
abiotic determinants such as alkalinity, NO3 and temperature. KW:

notion of ecosystem health has been widely adopted in environmental
policy, particularly in the management of river systems. Despite this,
even a notional understanding of ecosystem health and its assessment in
connected aquifer ecosystems remains elusive. In this article, we propose
a definition and provide a tiered framework for the assessment of
ecosystem health in groundwater. From the literature we identify general
attributes of a healthy groundwater ecosystem and from these develop
primary (Tier 1) indicators of health. Where Tier 1 benchmarks are
exceeded or more detailed assessment is required, we discuss a range of
indicators (Tier 2) that may together generate a multimetric index of
groundwater health. Our case study using samples from an alluvial
aquifer in north-western New South Wales, Australia, demonstrates the
utility of both tiers of the framework, and the ability of the approach to
separate disturbed and undisturbed sites. The process of multimetric

adaptable to site-specific contexts. KW: Groundwater, Ecosystem health,

2011. Molecular taxonomy and phylogenetic affinities of
two groundwater amphipods, Crangonyx islandicus and
Crymostygius thingvallensis, endemic to Iceland.
Molecular Phylogenetics and Evolution 58(3, March):527539. DOI: http://dx.doi.org/10.1016/j.ympev.2010.12.010.
ABS: The amphipod superfamily Crangonyctoidea is distributed
exclusively in freshwater habitats worldwide and is characteristic of
subterranean habitats. Two members of the family, Crangonyx islandicus
and Crymostygius thingvallensis, are endemic to Iceland and were
recently discovered in groundwater underneath lava fields. C. islandicus
belongs to a well-known genus with representatives both in North
America and in Eurasia. C. thingvallensis defines a new family,
Crymostygidae. Considering the incongruences observed recently
between molecular and morphological taxonomy within subterranean
species, we aim to assess the taxonomical status of the two species using
molecular data. Additionally, the study contributes to the phylogenetic
relationships among several crangonyctoidean species and specifically
among species from four genera of the family Crangonyctidae. Given the
available data we consider how the two Icelandic species could have
colonized Iceland, by comparing geographical origin of the species with
the phylogeny. Regions of two nuclear (18S and 28S rRNA) and two
mitochondrial genes (16S rRNA and COI) for 20 different species of
three families of the Crangonyctoidea were sequenced. Four different
methods were used to align the RNA gene sequences and phylogenetic
trees were constructed using bayesian and maximum likelihood analysis.
The Crangonyctidae monophyly is supported. C. islandicus appeared
more closely related to species from the Nearctic region. C. thingvallensis
is clearly divergent from the other species of Crangonyctoidea.
Crangonyx and Synurella genera are clearly polyphyletic and showed a
geographical association, being split into a Nearctic and a Palearctic
group. This research confirms that the studied species of Crangonyctidae
share a common ancestor, which was probably widespread in the
Northern hemisphere well before the break up of Laurasia. The Icelandic
species are of particular interest since Iceland emerged after the
separation of Eurasia and North America, is geographically isolated and
has repeatedly been covered by glaciers during the Ice Age. The close
relation between C. islandicus and North American species supports the
hypothesis of the Trans-Atlantic land bridge between Greenland and
Iceland which might have persisted until 6 million years ago. The status
of the family Crymostygidae is supported, whereas C. islandicus might
represent a new genus. As commonly observed in subterranean animals,
molecular and morphological taxonomy led to different conclusions,
probably due to convergent evolution of morphological traits. Our
molecular analysis suggests that the family Crangonyctidae needs
taxonomic
revisions.

Genetic differentiation between cave and surface-dwelling
populations of Garra barreimiae (Cyprinidae) in Oman.

ABS:
Background: Phenotypic similarities among cave-dwelling animals
displaying troglomorphic characters (e. g. reduced eyes and lack of
pigmentation) have induced a long-term discussion about the forces
driving convergent evolution. Here we introduce Garra barreimiae
Fowler & Steinitz, 1956, as an interesting system to study the evolution
of troglomorphic characters. The only hitherto known troglomorphic
population of this species lives in Al Hoota Cave (Sultanate of Oman)
close to a surface population. As a first approach, we assessed the genetic
differentiation between the two morphotypes of G. barreimiae to
determine whether gene flow still occurs. Results: We analysed the
mitochondrial control region (CR). In G. barreimiae the CR starts
immediately downstream of the tRNA-Thr gene, while the tRNA-Pro
gene is missing at this genomic location. Interestingly, a putative tRNAPro sequence is found within the CR. The phylogenetic analyses of the
CR sequences yielded a tree divided into three clades: Clade 1 has a high

Modifié le : 31.12.2011
genetic distance to the other clades and contains the individuals of three
populations which are separated by a watershed from all the others. Clade
2 comprises the individuals from Wadi Bani Khalid, the geographically
most remote population. Clade 3 comprises all other populations
investigated including that of Al Hoota Cave. The latter forms a
haplogroup which also includes individuals from the adjacent surface
population. Conclusions: Our data indicates that the troglomorphic cave
population is of quite recent origin supporting the hypothesis that
selection drives the fast evolution of troglomorphic traits. In this context
pleiotropic effects might play an important role as it has been shown for
Astyanax. There seems to be some gene flow from the cave population
into the adjacent surface populations. One blind individual, found at a
surface locality geographically distinct from Al Hoota Cave, is
genetically differentiated from the other blind specimens indicating the
probable existence of another cave population of G. barreimiae. The
phylogeographic analyses show that while some of the surface
populations are either still in contact or have been until recently, the
population Wadi Bani Khalid is genetically separated. One group
consisting of three populations is genetically highly differentiated
questioning the conspecifity with G. barreimiae.

The bat fly (Trichobius major) is a blood-feeding ectoparasite of the cave
myotis (Myotis velifer). A recent mitochondrial DNA (mtDNA) study
examining population structure of T. major in the South Central United
States detected a single haplotype from all individuals examined (N 48
from 12 different caves), representing one of only a few known examples
of such widespread mtDNA uniformity. We examined nuclear genetic
diversity using amplified fragment length polymorphism and detected
high levels of nuclear genetic diversity in all populations sampled.
Amplified fragment length polymorphism analyses indicated significant
levels of gene flow among caves >700 km apart, suggesting the absence
of mtDNA diversity in T. major is the result of a selective sweep, not a
demographic event (i. e., a recent bottleneck). One mechanism by which
mtDNA sweeps occur in arthropods is through bacterial parasites that
manipulate host reproduction and mtDNA inheritance. We used PCR to
test for the presence of all known reproductive parasites and detected a
widespread infection (91.33% infection rate) of T. major with a novel
Arsenophonus bacterium, as well as the infection of 2 individuals (1.16%
infection rate) with a novel strain of Rickettsia. We discuss the
implications for T. major phylogeography and the necessity of a
bigenomic approach in arthropod population genetics. KW: AFLP,

neilli using two mitochondrial markers (cytb, COI) and one nuclear
fragment (bfibr), in order to assess the influence of its endemicity to karst
habitat. One hundred fifteen individuals of L. neilli were collected in 20
localities throughout the geographic range of this species in Thailand.
Our study revealed strong geographic structure of the mtDNA genetic
diversity: six highly differentiated, allopatric genetic lineages were
observed in our dataset. They exhibit a very high degree of genetic
divergence, low gene flow among lineages and low levels of haplotype
and nucleotide diversities within lineages. Our results suggest that L.
neilli's populations are highly fragmented due to the scattered distribution
of its karst habitat. The most divergent lineage includes the populations
from western Thailand, which have been separated from the other genetic
lineages since at least the Early Pleistocene. The other lineages are more
closely related and have diverged since the Middle Pleistocene. This
study revealed an unexpected high level of genetic differentiation within
L. neilli and highlighted the high endemicity of this species to limestone
karsts. Our results enhance the importance of protecting limestone
habitats to preserve not only the species but also intraspecific diversity.

Leopoldamys neilli is a threatened murine rodent species endemic to
limestone karsts of Thailand. Twelve microsatellite loci were identified
using the method of microsatellite-enriched libraries. Polymorphism was
assessed in samples (N = 62) from four geographically distinct
populations in Thailand. Number of alleles per locus ranged from 9 to 15
(average 11.6). Observed and expected heterozygosities varied from 0.28
to 1.0 and from 0.44 to 0.91, respectively. There was no evidence for
linkage disequilibrium, however, four loci showed evidence of departure
from Hardy-Weinberg equilibrium in one population. Presence of null
alleles was not detected in all the 12 loci. These first microsatellites
primers developed for L. neilli will provide information on the fine-scale
genetic structure of this threatened species and will help in the
development of future conservation policies. KW: Leopoldamys neilli,

cave crickets Troglophilus cavicola and Troglophilus neglectus are the
most widely distributed European species of the family
Rhaphidophoridae. Their life cycles span two years. They overwinter
twice in caves in 4-6 months lasting diapause, T. cavicola in warmer
microhabitats. In caves, older T. cavicola undergo sexual maturation,
while T. neglectus do not. We hypothesized that the use of energysupplying compounds and reserve proteins in the fat body is more
extensive in T. cavicola than in T. neglectus. We analyzed the contents
and morphology of lipid droplets, glycogen rosettes and protein granula
at the beginning, the middle and the end of overwintering applying optic,
TEM and biochemical methods. In all individuals, the fat body is
composed of about 40 oval ribbons consisted of gradually changing
adipocytes and urocytes. T. cavicola use glycogen continuously, and stop
using lipids in the middle of overwintering, while this is inverse in T.
neglectus. Till the middle of overwintering, all individuals exploit
proteins, afterwards they are unevenly exploited. We found that the fat
body is differently engaged in metabolism of both cave crickets during
overwintering, supporting a more glycogen dependant metabolism in T.
cavicola, and a more lipid dependant one in T. neglectus. KW: Diapause,

Hipposideros terasensis (Hipposideridae), show little activity during
winter. It has never been determined whether in winter they exhibit
hibernation and multi-day periods of low body temperature. The
objectives of this study were to understand the winter activity pattern of
H. terasensis and to examine whether it enters hibernation during winter.
We monitored the skin temperature (T sk) of nine free-ranging H.
terasensis by attaching temperature-sensitive transmitters during the
winters of 2007-2008 and 2008-2009. The results showed that H.
terasensis entered hibernation from late December to early March. H.
terasensis, however, differs from temperate hibernating bats in several
ways: (1) it is capable of hibernation at roost temperature (T r) and T sk
>20°C; (2) hibernation at high T r and T sk does not lead to a relatively
high arousal frequency; and (3) adults do not increase body mass in
autumn prior to hibernation. To test the hypothesis that H. terasensis
feeds frequently during the hibernation period to compensate for the high
energetic demands of hibernating in warm hibernacula, we recorded the
number and timing of bats that emerged from and entered into a
hibernaculum, which contained more than 1000 bats. From 30 December
2007 to 29 February 2008, an average of only 8.4 bats (<1%) per night
(29 nights) emerged from the hibernaculum. Adult bats lost an average of
13-14% of body mass during an approximately 70-day hibernation
period. We suggest that H. terasensis might have remarkably low torpid
metabolic rates during hibernation. KW: Arousal, Body temperature,

examine genetic divergence within and between species of Tetracion we
sequenced part of the mitochondrial cytochrome oxidase 1 gene from 53
individuals from eleven caves across the range of Tetracion tennesseensis
and in the northern part of the range of Tetracion jonesi. We found: (1)
little variation within species (six haplotypes in Tetracion tennesseensis
and four haplotypes in Tetracion jonesi, with a maximum of 1.4%
intraspecific divergence between haplotypes), (2) that gene flow between
caves is limited (7 of 10 haplotypes were restricted to a single cave, and

between Tetracion tennesseensis and Tetracion jonesi). Our results are
consistent with previous morphology-based species definitions showing
Tetracion tennesseensis and Tetracion jonesi belonging to distinct taxa.
Our research contributes to the growing body of phylogeographic
information about cave species on the Cumberland Plateau, and provides

humpbacked long profile, made up of small transverse segments or plates,
in this case the tail extending towards the entrance. The dark blue-green
colour down the centre suggests that cyanobacterial growth follows the
track of the wind-deflected roof drip. The dry silty cave sediment
provides material for accretion onto the biological mat. This is the only

surface and subterranean species may be a key determinant for species
distributions. Until now, the existence of competition (including
predation) between these groups has not been tested. To assess the
coexistence and potential role of interspecific interactions between
surface Gammarus fossarum and subterranean Niphargus timavi, and to
determine their micro distributions, we conducted a series of field and
laboratory observations. We aimed to determine: (1) species substrate
preference, (2) whether the presence of G. fossarum influences the habitat
choice of N. timavi, and (3) possible predation effects on micro habitat
choice of small juveniles. Throughout a small river in SW Slovenia, N.
timavi was predominantly found in leaf litter and gravel, but rarely in
sand. In the sand however, we exclusively found juveniles. In contrast,
surface G. fossarum sheltered mainly in leaf litter. A similar, body size
dependent, micro distribution was observed in G. fossarum, where small
individuals were generally found in gravel and sand. The presence of G.
fossarum affected the micro distribution of juvenile, but not adult, N.
timavi. In the laboratory we observed predation and cannibalism in both
species. Niphargus timavi, however, appeared to be a more efficient
predator than G. fossarum. In particular, juvenile N. timavi were most
vulnerable to preying by adults of both species. This probably affected
the distribution of juvenile N. timavi that chose finer substrates when
placed with adult individuals in an aquarium with granules of different
size. To understand the distribution of subterranean species, the summed
effect of intraspecific interactions, as well as surface - subterranean
species interactions, in particular between individuals of different size,
should be taken into account. KW: Amphipoda, cannibalism,

thought to influence both the outcome of breeding attempts and breeding
behavior in colonial seabirds. We examined the relationship between nest
shelter in breeding Northern Fulmars (Fulmarus glacialis), at the remote
Cape Vera colony on Devon Island, Nunavut, Canada, and timing of
nesting, reproductive success, and the amounts of time parents spent in
different behaviors. Fulmars nesting in sheltered caves experienced lower
predation pressure and produced more chicks than Fulmars nesting on
exposed ledges. Experimental nests at such cave sites also had lower
depredation rates than experimental nests on ledges. There were no
differences between Fulmars at different nest types in their laying dates,
incubation shifts, incubation period, or the amount of time they allocated
to behaviors at the nest. Parents with nests at sheltered cave sites
appeared to have higher thermoregulatory costs. We postulate parental
experience is more important than costs associated with physical
characteristics of nest sites in influencing behavior of incubating Fulmars.

ABS: Bermuda has one of the highest concentrations of cave systems of
any country in the world. As the island's resident human population and
tourism expand, its unique subterranean habitats are becoming
increasingly threatened by development and eutrophication. The response
to nutrient enrichment of six macroalgal species found in Bermuda's
anchialine cave pools (landlocked body with a subterranean connection to
the ocean) was examined during summer of 2007. We used a combination
of nutrient bioassays, productivity measurements, and water quality
analysis. Ulva sp. (Chlorophyta) responded similarly across all nutrient
treatments (+N as 30 µM nitrate, +P as 2 µM phosphate, and +NP as 30
µM nitrate + 2 µM phosphate) at Calabash, which had dissolved
inorganic N (DIN):soluble reactive P (SRP) ratios of 13-16, whereas at
Harbour Pool, Ulva sp. responded best to the +N addition alone. The
latter was consistent with very low DIN:SRP (5.8) ratios indicative of
potential N limitation in this pool. P limitation was only detected in
nutrient assays conducted with Caulerpa mexicana (Chlorophyta)
collected from Cliff Pool, which had DIN:SRP ratios of 110. Halymenia
floresia (Rhodophyta) was found to be light rather than nutrient limited in
the Emerald cave pool. In some combinations of cave pools (e. g.
Grenadier and Deep Blue) and for some macroalgae [e. g. Caulerpa
racemosa (Chlorophyta), Caulerpia sertularioides (Chlorophyta), and
Cryptonemia sp. (Rhodophyta)], findings were not easily characterized
with measured parameters. Our findings illustrate the importance of
evaluating individual cave pools as well as individual macroalgal species
in each cave pool. Of the six macroalgae examined, Ulva sp. and H.
floresia showed the greatest potential as bioindicators for groundwater
quality in Bermudian caves. KW: Bermuda, Eutrophication,

Recent studies substantiate the importance of the unsaturated zone in
ground-water biodiversity of karst areas. Few investigations, however,
have addressed the temporal changes in community composition in
relation to water physico-chemical features. We provide information on
the distribution pattern of the fauna in dripping water at spatial and
temporal scales. This is related to variation in water chemistry and other
environmental features in five caves within two hydrographic basins of
the Pădurea Craiului Mountains (northwestern Romania). The analysis
revealed no major pollution in the dripping water. The physico-chemical
parameters varied within and between caves over one year. The dripping
water fauna is heterogeneously distributed within and between the caves,
containing a mixture of epigean and hypogean species. This emphasizes
high microhabitat partition and also underlines the influence of physicochemical parameters. The species composition among the two
hydrographic basins was different. Crustaceans are the best represented in
terms of both abundance and species richness. Six out of 15 crustacean
species are endemic to the Pădurea Craiului Mountains and four are new
to science. All these point to the importance of unsaturated karstic
habitats as biodiversity hot spots in ground-water ecosystems. KW:

http://dx.doi.org/10.1177/0748730410391947. ABS: Larvae
of the genus Arachnocampa, known as glowworms, are bioluminescent
predatory insects that use light to attract prey. One species,
Arachnocampa flava, is known to possess true circadian regulation of
bioluminescence: light:dark cycles entrain the rhythm of nocturnal
glowing. Given the absence of natural light as a cue in caves, we
addressed the question of whether cave populations of Arachnocampa
tasmaniensis, a species known to inhabit caves as well as epigean
environments, are rhythmic. We found that the major dark-zone cave
populations of A. tasmaniensis maintain a high-amplitude 24-hour rhythm
of bioluminescence, with the acrophase during external daylight hours.
Populations of A. tasmaniensis in caves many kilometers apart show
similar, but not exactly the same, timing of the acrophase. Systematic
investigation of colonies in the dark zone of a single cave showed that
some smaller colonies distant to the main ceiling colony, also in the dark
zone, glow in antiphase. Periodic monitoring of a single colony over
several years showed that the acrophase shifted from nocturnal to diurnal
some time between October 2008 and January 2009. Prey availability was
investigated as a possible zeitgeber. The acrophase of prey availability, as
measured by light trapping, and the acrophase of bioluminescence do not
precisely match, occurring 3 hours apart. Using in-cave artificial light

exposure, we show that after LD cycles, cave larvae become entrained to
bioluminesce during the foregoing photophase. In contrast, epigean larvae
exposed to artificial LD cycles after a period of DD become entrained to
bioluminesce during the foregoing scotophase. One explanation is that
individuals within colonies in the dark zone synchronize their
bioluminescence rhythms through detection and matching of each other's
bioluminescence. KW: Mutual synchronization, coupled oscillators,

purpose of this study was to examine the sensitivity, in a field situation,
of the hyporheic fauna to pollution by heavy metals and also to test the
use of oxidative stress enzymes produced by this fauna as a sensitive
indicator of oxidative stress generated by chemical contamination. This
was done by surveying the patterns of distribution, structure, and
composition of hyporheic invertebrate communities in one of the most
polluted rivers in Romania. Twelve permanent sampling stations with
differing water qualities were established along a 180 km transect of the
Arieş River. Data on hyporheic invertebrate abundance and richness,
chemistry of the surface and hyporheic water and interstitial suspended
particles were analyzed via multifactorial analyses. In the downstream,
more polluted stations, epigean species were less abundant and hyporheic
communities, especially macrocrustaceans and oligochetes, became
dominant. The higher levels of hyporheic invertebrate biodiversity in the
moderately polluted stations compared to highly polluted, and the
increase of the number of some hyporheos (especially macrocrustaceans)
in the moderately polluted stations, suggested that the hyporheic fauna
was more tolerant of heavy metal pollution than the surface water fauna
of the area. However, the different richness and abundance of hyporheic
Publications 2011-1

fauna in sites of similar water chemistry suggested that additional factors,
such as sediment structure are shaping the spatial distribution of
hyporheic fauna. Strong correlations between superoxide dismutase

suggest that oxidative stress enzymes may prove to be sensitive indicators
of chemical pollution in hyporheic zones. KW: Interstitial fauna,

together with environmental data, on seven sampling occasions from June
2004 to May 2005, at two river reaches-at the site of in-stream gravel
extraction and at a site 2.5 km upstream. The hyporheic samples were
taken from the river bed and from the gravel bars extending laterally from
the stream channel. The invertebrate community was dominated by insect
larvae (occasional hyporheos), followed by meiofauna (permanent
hyporheos). Stygobionts were present at low species richness and in low
densities. Gravel extraction from the stream channel led to changes in the
patterns of water exchange between surface and subsurface and changes
in the sediment composition at the site. Immediate reductions in density
and taxonomic richness of invertebrates were observed, together with
changes in their community composition. The hyporheic invertebrate
community in the river recovered relatively fast (in 2.5 months) by means
of density and taxonomic richness, while by means of community
composition invertebrates needed 5-7 months to recover. The impact of
fine sediments (<0.1 mm) on biofilm activity measured through ETS
activity and hyporheic invertebrate density and taxonomic richness was
strongly confirmed in this study. KW: Disturbance, In-stream gravel

more humid habitats, namely the bottom of the valley, the adjacent north
facing slope, terraces on the north facing slope, and caves. The vegetation
cover also appeared to be important for resting habitats; on the bottom of

1. The functional feeding group approach has been widely used to
describe the community structure of benthic invertebrates in relation to
organic matter resources. Based on this functional framework, positive
interactions between feeding groups (especially shredders and collectorgatherers) were postulated in the River Continuum Concept. However,
relationships with organic matter have been poorly documented for
invertebrates living in the hyporheic zone. 2. We hypothesised that the
common subterranean amphipod Niphargus rhenorhodanensis would
feed on fine particulate organic matter (FPOM), which is more abundant
than coarse particulate organic matter (CPOM) in hyporheic habitats, and
should be favoured by the occurrence of shredders that produce FPOM
from CPOM. 3. We used laboratory experiments to quantify leaf litter
processing by N. rhenorhodanensis and a common shredder, the surface
amphipod Gammarus roeselii. We estimated rates of feeding and
assimilation (using nitrogen stable isotopes) of the two species separately
and together to reveal any potential shredder-collector facilitation
between them. 4. Measured leaf litter mass loss showed that N.
rhenorhodanensis did not act as a shredder, unlike G. roeselii. Organic
matter dynamics and 15N/14N ratios in tissues of niphargids indicated
that N. rhenorhodanensis was a collector-gatherer feeding preferentially
on FPOM. We also found a positive influence of the gammarid shredders
on the assimilation rate of N. rhenorhodanensis, which fed on FPOM
produced by the shredders, supporting the hypothesis of a positive
interaction between surface shredders and hyporheic collector-gatherers.

Survival and Growth of the Stygophilic Amphipod
Gammarus troglophilus Under Laboratory Conditions.
Journal of Crustacean Biology 31(3, July):424-433. DOI:
http://dx.doi.org/10.1651/10-3431.1. ABS: Amphipods play
important roles in the cycling of nutrients and energy in many aquatic
systems where they display a wide range of feeding modes ranging from
detritivore to predator. Although the biology of many amphipod species
has been examined, little is known of hypogean amphipods inhabiting
cave streams. Gammarus troglophilus is a stygophilic amphipod that cooccurs with the federally endangered stygobiont G. acherondytes in cave
streams of the Salem Plateau Karst Region of southwestern Illinois. With
the goal to establish a self-sustaining laboratory population of cave
amphipods to obtain amphipods for lethality experiments, we tested
hypotheses relating the survival and growth rates of G. troglophilus
collected from cave streams to different laboratory conditions of food and
water velocity. We used a series of microcosm experiments to test the
hypotheses that survival and growth are not affected by type of water
Publications 2011-1
Page 29 sur 44
(cave water vs. amended water), water velocity (static vs.
dynamic/recirculating), or the type of available food (sediment vs.
sediment, leaf discs, and TetraMin®). We also tested if different food
treatments affected the survival and/or growth of juvenile amphipods and
newly released neonates in static chambers. Our results indicate that cave
water was important for survival because no amphipods survived past 30
days in experiments with water amended to resemble cave water. The
addition of food (leaf discs and TetraMin®) and water velocity affected
survival but not growth rates in microcosm experiments. Food treatment
(leaf discs vs. TetraMin®) did not significantly affect survival or growth
rates of juvenile amphipods. However, leaf discs increased the survival

DOI:
A major challenge facing biodiversity conservation and management is
that a significant portion of species diversity remains undiscovered or
undescribed. This is particularly evident in subterranean animals in which
species delimitation based on morphology is difficult because
differentiation is often obscured by phenotypic convergence. Multilocus
genetic data constitute a valuable source of information for species
delimitation in such organisms, but until recently, few methods were
available to objectively test species delimitation hypotheses using genetic
data. Here, we use recently developed methods for discovering and
testing species boundaries and relationships using a multilocus dataset in
a widely distributed subterranean teleost fish, Typhlichthys subterraneus,
endemic to Eastern North America. We provide evidence that species
diversity in T. subterraneus is currently underestimated and that the
picture of a single, widely distributed species is not supported. Rather,
several morphologically cryptic lineages comprise the diversity in this
clade, including support for the recognition of T. eigenmanni. The high
number of cryptic species in Typhlichthys highlights the utility of
multilocus genetic data in delimiting species, particularly in lineages that
exhibit slight morphological disparity, such as subterranean organisms.
However, results depend on sampling of individuals and loci; this issue
needs further study. KW: Bayesian, cave, conservation, phylogenetics,

charon n. sp. is close to two troglobiomorphic species, M. infernalis and
M. alegrei (new comb.), sharing the same aedeagus morphology. These
three species constitute a monophyletic group that is hypothesized as
originating in the endogean environment of the southern end of the
Iberian Mountain Range, around the Valencia trough. These three species
live in caves that were possibly isolated by the Miocene basins. The
analysis of key morphological characters in the Microtyphlus phyletic
series showed that the slenderness of appendages, that defines taxa as
Speleotyphlus and Aphaenotyphlus, are of little phylogenetic value, as
this also happens with other troglobiomorphic features (e. g.,
depigmentation). However, other morphological characteristics (male
aedeagus, chaetotaxy, labial tooth) suggest a close relationship between
Microtyphlus, Speleotyphlus and Aphaenotyphlus, which leads us to
propose the last two taxa as synonyms of Microtyphlus. KW: Arthropoda,

lasted 81 days from egg laying in early November to fledging in middle
to late January. Clutch size ranged from one to two eggs which were
incubated for an average of 22 days. Nestlings remained in nests for an
average of 44 days and fledglings remained at the site for 5 additional
days. These observations provide new information on nesting sites used
by S. zonaris in Argentina, and provide the first documentation of the
length of the breeding phases for the species in South America. The
"apparently shortened" length of incubation and nestling periods may be a
geographical effect, due to this being the most southeastern known

The mating system of the Mediterranean monk seal was studied
combining the use of diverse technologies. Sexual dimorphism in size
was limited. Sexual activity was only observed to occur in the water. The
different segments of the population segregated spatially: females, pups,
and juveniles aggregated inside two main caves, whose entrances were
controlled by a small number (2-3) of territorial males that defended
aquatic territories situated at the very mouth of the caves. Other territorial
males defended aquatic territories located further away (5-30 km). The
tenure of aquatic territories was nonseasonal and spanned several years.
Relatedness among pups belonging to the same cohort was low or null,
indicating a low level of polygyny, which is not surprising for an
aquatically mating phocid with a protracted reproductive season.
However, in addition, genetic relatedness showed a remarkable temporal
periodicity. These results in combination point to the existence of a
complex social structure in this species.

species richness was observed in the mid-elevation cave. Bat activity was

occurred earlier at high elevation than at lower elevations. Activity of
boreal-alpine species, such as Eptesicus nilssonii, peaked at the start of
the swarming period, that of species typical of lower elevations, such as
Myotis emarginatus, peaked in the middle of the swarming season. In a
few species, males showed a significant preference for higher altitude
caves, in contrast to females. A similar pattern was observed in the
proportion of adults to juveniles, which increased with increasing

Within the soil matrix and underlying rock, cracks and fissures and other
air-filled spaces between rocks, sometimes called the milieu souterrain
superficiel (MSS), are present in a variety of geological contexts. We
examined year-long hourly temperature profiles at sites in lava in the
Canary Islands and limestone in Slovenia. All sites had species that show
morphological adaptations usually associated with cave-dwelling
organisms, including elongated appendages and reduced eyes and
pigment. MSS sites were studied at depths between 10 and 70 cm and
showed strong seasonality, and most had a discernible diurnal cycle as
well. The most striking difference from surface habitats was that the
temperature extremes were much less pronounced in MSS sites.
Temperature variability was not correlated with troglobiotic species
richness. The presence of species with similar morphologies to those
found in caves indicates that selective pressures are similar in cave and
shallow subterranean habitats. KW: Hypogean habitats, milieu souterrain

sinkholes have identified complex food webs dependent on detrital and,
in some cases, chemosynthetically produced organic matter.
Chemosynthetic microbes in anchialine systems obtain energy from
reduced compounds produced during organic matter degradation (e. g.,
sulfide, ammonium, and methane), similar to what occurs in deep ocean
cold seeps and mud volcanoes, but distinct from dominant processes
operating at hydrothermal vents and sulfurous mineral caves where the
primary energy source is mantle derived. This review includes case
studies from both anchialine and non-anchialine habitats, where evidence
for in situ chemosynthetic production of organic matter and its
subsequent transfer to higher trophic level metazoans is documented. The
energy sources and pathways identified are synthesized to develop
conceptual models for elemental cycles and energy cascades that occur
within oligotrophic and eutrophic anchialine caves. Strategies and
techniques for testing the hypothesis of chemosynthesis as an active
process in anchialine caves are also suggested. KW: Anchialine cave,

réf. ABS: Amphicutis stygobita is a new genus and new species of
ophiuroid found in Bernier Cave, an anchialine cave on San Salvador
Island, Bahamas. The species is small (disk diameter 3-4 mm) with short
arms (2-2.5X disk diameter). Dorsal disk features include imbricated
scales, and oval radial shields separated by a column of scales. Ventral
disk features include imbricated scales, genital scales flat and thin, no
bursal sacs, second tentacle pore of oral frame outside mouth slit, oral
shields small ovals similar in appearance to disk scales, two to three oral
papillae per jaw side with the proximal papillae usually in the infradental
position, and ventral tooth at the apex of each jaw broadly rounded. The
arms are the most distinctive feature. Dorsal arm plates are small
diamond-oval shaped and separated from one another by a gap equal to
the arm plate length. Ventral arm plates are small figure-8 shaped and
separated from one another by a gap equal to the arm plate length. Lateral
arm plates meet medially on dorsal and ventral sides and make up most of
an arm segment. Each lateral arm plate bears two arm spines. Disk and
arms are often formed by soft tissue outlining plates and scales, but
lacking significant calcification. A raised skin persists after calcification,
from which the genus name derives. The species is named for its aquatic
cave-dwelling habit, apparently endemic to a single cave, and may be
unique among ophiuroids in being restricted to a cave environment. KW:

Aerobiology of caves is still in its infancy. At present, no clear
information has been generated on the limits of acceptance of fungal
spores in air which permit classification of the atmosphere of a cave as
not dangerous for the conservation of rock-art paintings. We had the
unique opportunity to visit and sample different caves in Spain and
France, under different managements. We obtained a collection of data
related with contamination episodes that permitted the formulation of a
tentative index of fungal hazard in show caves. This is supported by the
concentration of fungal spores in the cave air, the knowledge of the cave
history and management, and a detailed survey of the different halls of
the caves. The index classifies the risks into five categories: category 1
identifies a cave without fungal problems, category 2 is an alarm signal
for caves, category 3 is a cave threatened by fungi, category 4 is assigned
to a cave already affected by fungi, and category 5 is a cave with an
irreversible ecological disturbance. This index, a working hypothesis, is
launched to promote interest and forum discussion and should be
validated by the scientific community after being updated with more
surveys and cave analyses carried out under different managements and
with different contamination episodes. Highlights: We studied the
aerobiology of five caves with different contamination and management
regimes. Data permitted to propose an index of fungal hazard. Caves are
classified into five categories from no problem to irreversible ecological
disturbance. KW: Aerobiology, Show caves, Fungi, Fungal outbreaks.

influence of bacterial communities on the formation of carbonate deposits
such as moonmilk was investigated in Altamira Cave (Spain). The study
focuses on the relationship between the bacterial communities at
moonmilk deposits and those forming white colonizations, which develop
sporadically throughout the cave. Using molecular fingerprinting of the
metabolically active bacterial communities detected through RNA
analyses, the development of white colonizations and moonmilk deposits
showed similar bacterial profiles. White colonizations were able to raise
the pH as a result of their metabolism (reaching in situ pH values above
8.5), which was proportional to the nutrient supply. Bacterial activity was
analyzed by nanorespirometry showing higher metabolic activity from
bacterial colonizations than uncolonized areas. Once carbonate deposits
were formed, bacterial activity decreased drastically (down to 5.7% of the
white colonization activity). This study reports on a specific type of
bacterial community leading to moonmilk deposit formation in a cave
environment as a result of bacterial metabolism. The consequence of this
process is a macroscopic phenomenon of visible carbonate depositions
and accumulation in cave environments.

DOI:
Chronic environmental stress is known to induce evolutionary change.
Here, we assessed male life-history trait divergence in the neotropical fish
Poecilia mexicana from a system that has been described to undergo
incipient ecological speciation in adjacent, but reproductively isolated
toxic⁄nontoxic and surface⁄cave habitats. Examining both field-caught and
common garden-reared specimens, we investigated the extent of
differentiation and plasticity of lifehistory strategies employed by male P.
mexicana. We found strong site-specific life-history divergence in traits
such as fat content, standard length and gonadosomatic index. The
majority of site-specific life-history differences were also expressed
under common garden-rearing conditions. We propose that apparent
conservatism of male life histories is the result of other (genetically
based) changes in physiology and behaviour between populations.
Together with the results from previous studies, this is strong evidence
for local adaptation as a result of ecologically based divergent selection.

DOI:
http://dx.doi.org/10.1098/rsbl.2011.0237. ABS: Divergent
selection through biotic factors like predation or parasitism can promote
reproductive isolation even in the absence of geographical barriers. On
the other hand, evidence for a role of adaptation to abiotic factors during
ecological speciation in animals is scant. In particular, the role played by
perpetual darkness in establishing reproductive isolation in cave animals
(troglobites) remains elusive. We focused on two reproductively isolated
ecotypes (surface- and cave-dwelling) of the widespread livebearer
Poecilia mexicana, and raised offspring of wild-caught females to sexual
maturity in a 12-month common-garden experiment. Fish were reared in
light or darkness combined with high- or low-food conditions. Females,
but not males, of the surface ecotype suffered from almost complete
reproductive failure in darkness, especially in the low-food treatment.
Furthermore, surface fish suffered from a significantly higher rate of
spontaneous, stress-related infection with bacterial columnaris disease.
This experimental evidence for strong selection by permanent darkness
on non-adapted surface-dwelling animals adds depth to our understanding
of the selective forces establishing and maintaining reproductive isolation
in cave faunas. ABS: Cave fauna, ecological speciation, life-history

this species as a roost. We took this opportunity to (1) identify the leaves
consumed by this poorly known Neotropical bat species, and (2) test
whether folivory is a temporal phenomenon, such as in other leaf-eating
bat species. Artibeus amplus consumes the leaves of seven species of
plants, and four of these were found in every month of the year during the
study. We report for the first time: (1) folivory in A. amplus, (2) five plant
species never reported before in the diet of a bat, and (3) folivory as a

fecundity and survival probability associated with intra-sex variation in
body size was studied in Mesophylax aspersus, a caddisfly species with
female-biased sexual size dimorphism, which inhabits temporary streams
and aestivates in caves. Adults of this species do not feed and females
have to mature eggs during aestivation. 2. Thus, females of larger size
should have a fitness advantage because they can harbour more energy
reserves that could influence fecundity and probability of survival until
reproduction. In contrast, males of smaller size might have competitive
advantages over others in mating success. 3. These hypotheses were
tested by comparing the sex ratio and body size of individuals captured
before and after the aestivation period. The associations between body
size and female fecundity, and between mating success and body size of
males, were explored under laboratory conditions. 4. During the
aestivation period, the sex ratio changed from 1:1 to male biased (4:1),
Publications 2011-1
Page 35 sur 44
and a directional selection on body size was detected for females but not
for males. Moreover, larger clutches were laid by females of larger size.
Finally, differences in mating success between small and large males
were not detected. These results suggest that natural selection (i. e. the
differential mortality of females associated with body size) together with
possible fecundity advantages, are important factors responsible of the
sexual size dimorphism of M. aspersus. 5. These results highlight the
importance of taking into account mechanisms other than those
traditionally used to explain sexual dimorphism. Natural selection acting
on sources of variation, such as survival, may be as important as
fecundity and sexual selection in driving the evolution of sexual size
dimorphism. KW: Body size, caves, mating behaviour, sex ratio, sexual

resource subsidies can greatly affect the composition and dynamics of
recipient communities. Caves are especially tractable for studying spatial
subsidies because primary productivity is absent. Here, we performed an
ecosystem-level manipulation experiment to test the direct influence of
detrital subsidies on community structure in terrestrial cave ecosystems.
After performing baseline censuses of invertebrates, we removed all
organic material from 12 caves and constructed exclusion boxes to
prevent natural resource inputs. Next, we stocked each cave with
standardized quantities of two major natural subsidies to caves: leaves
(leaf packs) and carcasses (commercially supplied rodents), and measured
the invertebrate colonization and utilization of these resources for 23
months. Over the course of the experiment, 102 morphospecies were
observed. Diplopods and collembolans were most abundant on leaf packs,
and dipteran larvae and collembolans were most abundant on the rats. On
average, caves receiving either treatment did not differ in species
richness, but abundance was significantly higher in rat caves over both
the duration of the experiment and the temporal "life" of the individual
resources, which were restocked upon exhaustion. Post-manipulation
invertebrate communities differed predictably depending on the type of
subsidy introduced. Over the course of the experiment, caves that
received the same subsidy clustered together based on community
composition. In addition, the invertebrate community utilizing the
resource changed over the duration of the two-year experiment, and
evidence of succession (i. e., directional change) was observed. Results
from this study demonstrate how allochthonous resources can drive the
community dynamics of terrestrial invertebrates in cave ecosystems and
highlight the need for consideration of the surface environment when
managing and protecting these unique habitats. KW: Allochthonous

insects that are restricted to cool temperate forests and mountainous
regions. Morphologically distinguishable species are similar ecologically
and show narrow endemism and a patchy distribution. As a result,
grylloblattids are hypothesized to be relict species that have persisted in
situ over long periods of climatic and geological change (Storozhenko &
Oliger, 1984). We investigate whether the diversification pattern of Asian
grylloblattids reflects long-term persistence and divergence due to
geological events, or more recent diversification in response to climatic
change. Using multilocus genetic data, we examine the phylogenetic
relationship to other Asian Grylloblattidae and the geographic pattern of
diversification of Korean rock-crawlers, Galloisiana Caudell & King
(1924) and Namkungia Storozhenko & Park (2002). Our analysis reveals
a monophyletic grouping of Korean species, with multiple cryptic
lineages and restricted geographical distributions. Based on genetic data,
Korean species are closely related to Japanese Galloisiana. Using a
Bayesian relaxed clock model calibrated with a mitochondrial
substitution rate, the age of the most recent common ancestor of the
Korean-Japanese lineage is estimated within the Miocene epoch. This
provides evidence for a diversification event closely tied to the geological
events separating the Japanese archipelago from the Korean peninsula.

"Eugenio Boegan" 43:103-115. RIAS: Dopo una premessa sui
vari aspetti (geomorfologici, climatici, vegetazionali e storici) dell'Antro
di Casali Neri (Grotta sul Monte San Michele, 326/450 VG, Comune di
Savogna, Carso isontino), vengono prese in considerazione le Briofite
presenti all'ingresso della cavità e nella dolina al fondo della quale si apre
l'ipogeo. Per ciascuna delle 32 specie (7 epatiche e 25 muschi), rinvenute
nel singolare ambiente cavernicolo, sono indicati il substrato, l'elemento
corologico, la strategia di vita e le esigenze di luce, concordemente con
precedenti osservazioni e ricerche effettuate in varie cavità del Carso
triestino. Nel corso dell'indagine è apparso interessante il rinvenimento di
Bryum moravicum (= B. laevipilum), muschio per il quale esisteva
soltanto una segnalazione risalente peraltro all'inizio del secolo scorso.
Continua con il presente contributo l'indagine sulla brioflora delle cavità
carsiche, sia di quelle presenti sull'altipiano triestino che di quelle che si
aprono nel territorio isontino. Scopo essenziale di questa, e di future
ricerche, è quello di fornire un quadro il più significativo possibile sulla
presenza e sull'identità, nella regione Friuli Venezia Giulia, delle Briofite,
gruppo di vegetali ancor poco osservato e studiato. SUM: After a
preliminary statement about the different aspects (geomorphologycal,
climatic, vegetational and historical) of the Casali Neri Cavern (Cave on
the Mount Saint Michael, 326/450 VG, Savogna, Isonzo Karst), the
Bryophytes, present at the cavity entrance and at the end of the dolina
where the hypogeum opens, are considered. The substratum,
chorologycal element, life strategy and light exigency - according to
former observations and researches in some cavities of the Trieste Karst are pointed out for each of the 32 species (7 liverworts and 25 mosses)
found in the singulare cave milieu. During the research it seemed
interesting the finding of Bryum moravicum (= B. laevipilum), a moss
with only one recording in Friuli Venezia Giulia region, dated back at the
beginning of the last century. The investigation on the Karst cavities
Bryoflora (both on Trieste plateau and on Isonzo territory) goes on with
the present notes. The aim of this researches (and future ones) is to supply
an as much as possible significant outline of the presence and the identity,

DOI:
http://dx.doi.org/10.1007/s10531-011-0057-5. ABS: In Brazil,
only limestone caves and a few caves in sandstone, iron ore and granite
rocks had their invertebrate communities evaluated. Being such, the
present study aimed to promote a comparative analysis of the structure of
the invertebrate communities in caves associated to carbonatic, magmatic,
siliciclastic and ferruginous rocks of the Brazilian Atlantic forest.
Significant differences in the relative richness, abundance and diversity
were observed between lithologies. The average relative richness was
higher in the ferruginous caves (0.53 spp). The total number of
troglomorphic species was significantly different among caves and the
highest average richness occurred at ferruginous caves (5.79 spp/cave).
Siliciclastic, carbonatic and magmatic caves presented a higher

quantitative similarity of the fauna. Ferruginous caves revealed
communities with a fauna composition different from the other
lithologies. The total richness of invertebrates correlated significantly and
positively with the linear development in the siliciclastic caves (Rs =
0.67, P<0.05), carbonatic (Rs = 0.71, P<0.05) and ferruginous (Rs = 0.74,
P<0.05). The rock type in which the cave is inserted can determine
differences in the richness of invertebrate troglophyles and troglobites.
Therefore, on creating value attributes, the size of the caves should
always come related to their lithology by the fact that same sized caves
associated to different lithologies, possess communities with quite diverse
structures. KW: Caves, Invertebrates, Diversity, Litology, Atlantic Forest.

structure of hibernating bat communities has been studied in eight
artificial caves of Samarskaya Luka differing in size and layout. Three
types of the relative abundance distribution (RAD) of species in these
communities have been revealed. Conditions for hibernation are most
favorable in large caves with a stable microclimate, where the abundance
of bats is high, the Shannon index has the peak values, and variation in
the index of species evenness is the lowest. In such caves, RAD fits the
broken-stick and log-series models. Variation in diversity indices reaches
the highest level in shallow adits with a changeable microclimate, where
RAD fits the geometric series model. The abundance, diversity, and
structure of communities depend mainly on cave size and the presence of
absence of drafts and, to a lesser extent, on ambient temperature,
availability of microshelters, and the type of landscape surrounding the
cave. Anthropogenic factors have a weak effect only on the abundance of
individual species (M. nattereri, M. daubentonii, M. dasycneme, and E.
nilssonii) but not on the overall diversity of bat communities. KW: Bats,

in other Callipodida. Peripheral characters such as the relative lengths of
antennomeres, the number of ocelli, the number of pleurotergites or even
the shape of paraprocts and the coloration seem to provide more
information for the distinction of the species than do the relatively
uniform gonopods. The differences in gonopods mainly concern the
shape and length of cannula, the length and shape of coxal processes g
and k, and the number of the acicular projections of the femoroid. An
explanation is offered for the function of the trochanteral lobe of 9th legpair. It provides mechanical support for the cannula and seems to assist
sperm charge and insemination during copulation. An identification key
to the species in the genus is produced to accommodate the new species.

presents an adaptive challenge to troglobitic organisms. The mechanisms
by which natural selection modify an ancestral surface neural circuit to
produce a novel subterranean behavior remain a mystery. To address this
question, we performed cross species microarray experiments to compare
differences in gene expression levels in the adult brain of the teleost
Astyanax mexicanus. This species provides a unique opportunity for
comparative genetic studies as it consists of extant epigean (surface) and
hypogean (cave) conspecifics. Microarray experiments herein revealed
significant changes in transcription levels of seventeen genes, several of
which are important for behaviors involved in metabolic management.
We focused on genes central to three neurotransmission and
neuromodulation networks: the endocannabinoid system (Cannabinoid
receptor
CB1),
the
dopaminergic
system
(Tyrosine
3monooxygenase/tryptophan 5-monooxygenase activation protein) and the
glutamatergic system (glutamate receptor AMPA 2a). All three genes
were upregulated in the hypogean form of A. mexicanus compared to the
epigean form, indicating that behavioral differences in the hypogean form
of the species could be due to alterations in expression levels of several
key genes. This information provides insights into the complex
relationships among environmental factors, genetics, nervous systems and
adaptive behavior, and can subsequently help us understand how these
interactions affect behavior in other biological systems. KW: Brain,

Spatial variability in the hyporheic zone refugium of
temporary streams. Aquatic Sciences - Research Across
Boundaries, Online First™, 29 April 2011. This article
belongs to the Special Issue "Recent Perspectives on
Temporary
River
Ecology".
DOI:
http://dx.doi.org/10.1007/s00027-011-0203-x. ABS: A key
ecological role hypothesized for the hyporheic zone is as a refugium that
promotes survival of benthic invertebrates during adverse conditions in
the surface stream. Many studies have investigated use of the hyporheic
refugium during hydrological extremes (spates and streambed drying),
and recent research has linked an increase in the abundance of benthic
invertebrates within hyporheic sediments to increasing biotic interactions
during flow recession in a temporary stream. This study examined spatial
variability in the refugial capacity of the hyporheic zone in two
groundwater-dominated streams in which flow permanence varied over
small areas. Two non-insect taxa, Gammarus pulex and Polycelis spp.
were common to both streams and were investigated in detail.
Hydrological conditions in both streams comprised a four-month period

of flow recession and low flows, accompanied by reductions in water
depth and wetted width. Consequent declines in submerged benthic
habitat availability were associated with increases in population densities
of mobile benthic taxa, in particular G. pulex. The reduction in the spatial
extent of the hyporheic zone was minimal, and this habitat was therefore
a potential refugium from increasing biotic interactions in the benthic
sediments. Concurrent increases in the hyporheic abundance and
hyporheic proportion of a taxon's total (benthic + hyporheic) population
were considered as evidence of active refugium use. Such evidence was
species-specific and site-specific, with refugium use being observed only
for G. pulex and at sites dominated by downwelling water. A conceptual
model of spatial variability in the refugial capacity of the hyporheic zone
during habitat contraction is presented, which highlights the potential
importance of the direction of hydrologic exchange. KW: Hyporheic

Essai d'analyse critique des principales hypothèses
concernant la phylogénie des Malacostracés (Crustacea,
Malacostraca). Travaux de l'Institut de Spéologie "Émile
Racovitza" 50:87-119. ABS: Malacostraca, as a Class, represents
the largest taxonomic group within the Subphylum Crustacea. This essay
is a contribution to the perennial debate of the way to classify the more
than 40000 malacostracan species. The various opinions on the way
generations of carcinologists systematised Malacostraca in Orders and
Superorders is synthetically reviewed. Because of the variety and
contrasting opinions a reanalysis of the large carcinological data using a
strict phylogenetic framework is presented. It is assumed that
Malacostraca is a monophyletic group and within its system one deals, a
priori, with monophyletic orders. With this assumption at hand a cladistic
analysis of 17 orders and 68 morphological traits is presented. The
analysis was done using the Wagner parsimony algorithm implemented in
the computer programme PAUP 4.10. Based on 37 informative
characters, an unrooted tree with a length of 101 steps was obtained. The
results are discussed at long comparing the present data with diverse
opinions on the phylogenetic affinities of the Malacostraca main groups.
It is especially emphasised the significance of the present results for a
new framework of the Malacostraca phylogeny and systematics. The
following major conclusions emerge: (1) Phylocarida (Order Leptostraca)
represents a basal group of Malacostraca separated early from its sistergroup Eumalacostraca; (2) this latter group constitutes the major stock of
Malacostraca; (3) the Syncarida does not represent a monophylum
because Bathynelacea is a well individuated basal group of
Eumalocostraca. Hence, it is proposed to accept the taxonomic solution of
SERBAN (1970) who defined this group as the Superorder
Podophalocarida; (4) the Hoplocarida is a collateral stem detached very
early from the Eumalacostraca; it presents a mosaic of primitive and
advanced (original) morphological traits; (5) the sister-group of
Hoplocarida is formed by the bundle of lineages Anaspidacea +
Neocarida + Eucarida, representing a major component of
Eumalacostraca and which could be assimilated to the taxon Caridoida
(however, without including the Bathynellacea); (6) Anaspidacea is the
only group of the Superorder Syncarida, the most primitive branch of the
Caridoida s. str.; (7) Thermosbaenacea is a well individuated lineage,
taxonomically ranked as Superorder Pancarida, the sister-group of the
Peracarida; (8) the Neocarida (Pancarida + Peracarida) represents, most
probably, the sister-group of Syncarida (Anaspidacea) and the bundle
Syncarida + Neocarida forms the sister-group of Eucarida; (9)
Amphipoda and Isopoda do not represent sister-groups; Amphipoda is a
more primitive group having affinities to the bundle of lineages united in
the taxon Mancoida; both taxa are sister-groups. KW: Crustacea,

Convergent Patterns of Body Shape Differentiation in Four
Different Clades of Poeciliid Fishes Inhabiting Sulfide
Springs. Evolutionary Biology 38(4, December):412-421.
We investigated replicated differentiation in four lineages of livebearing
fishes (two with the genus Poecilia and two within Gambusia), which
inhabit freshwater habitats and have also colonized sulfide springs in
Oklahoma, Mexico, and Venezuela. Sulfide springs are characterized by
extreme hypoxia and high concentrations of toxic hydrogen sulfide,
which provide a strong source of divergent selection compared to
adjacent non-sulfidic habitats. Using geometric morphometric analysis of
body shape, we found that sulfide spring populations significantly differ
from relatives from regular freshwater habitats in all four lineages
investigated. Differentiation is characterized by strong patterns of
convergent evolution, with sulfide spring populations consistently
exhibiting an increase in head size, even though the magnitude and nature
differences varied across lineages. Head size is strongly correlated with
an increase in gill size in sulfide spring populations of the genus Poecilia,
which facilitates efficient oxygen acquisition in the hypoxic H2Senvironment and directly affects survival. The convergent patterns of
differentiation support previous findings about the effects of sulfide on
trait evolution. KW: Adaptation, Convergent evolution, Divergent

The
millipede genus Sinocallipus is reviewed, with four new cave-dwelling
species, Sinocallipus catba, Sinocallipus deharvengi, Sinocallipus jaegeri
and Sinocallipus steineri, being described from caves in Laos and
Vietnam. With the new records the number of species in the genus
reaches six and the genus range is extended to Central Vietnam and North
and Central Laos. Both, Sinocallipus jaegeri from Khammouan Province
in Laos and Sinocallipus simplipodicus Zhang, 1993 from Yunnan,
China, show high level of reduction of eyes, which has not been recorded
in other Callipodida. Peripheral characters such as the relative lengths of
antennomeres, the number of ocelli, the number of pleurotergites or even
the shape of paraprocts and the coloration seem to provide more
information for the distinction of the species than do the relatively
uniform gonopods. The differences in gonopods mainly concern the
shape and length of cannula, the length and shape of coxal processes g
and k, and the number of the acicular projections of the femoroid. An
explanation is offered for the function of the trochanteral lobe of 9th legpair. It provides mechanical support for the cannula and seems to assist
sperm charge and insemination during copulation. An identification key
to the species in the genus is produced to accommodate the new species.

locations (Côte Bleue vs. Calanques). Overall, 240 apical tips from

gonads per polyp in male colonies. The fecundity of red coral varied
significantly for populations dwelling in different cave zones and
geographic areas but not for the examined depths. Our results contribute
to the knowledge of red coral fecundity in populations not yet studied in
the NW Mediterranean and elucidate significant variability in fecundity
within different environmental conditions. The information on coral
fecundity can contribute to the development of management and
conservation plans for red coral populations.

Kartchner Caverns, located near Benson, Arizona, USA, is an active
carbonate cave that serves as the major attraction for Kartchner Caverns
State Park. Low-impact development and maintenance have preserved
prediscovery macroscopic cavern features and minimized disturbances to
biological communities within the cave. The goal of this study was to
examine fungal diversity in Kartchner Caverns on actively-forming
speleothem surfaces. Fifteen formations were sampled from five sites
across the cave. Richness was assessed using standard culture-based
fungal isolation techniques. A culture-independent analysis using
denaturing gradient gel electrophoresis (DGGE) was used to assay
evidence of community homogeneity across the cave through the
separation of 18S rDNA amplicons from speleothem community DNA.
The culturing effort recovered 53 distinct morphological taxonomic units
(MTUs), corresponding to 43 genetic taxonomic units (GTUs) that
represented 21 genera. From the observed MTU accumulation curve and
the projected total MTU richness curve, it is estimated that 51 percent of
the actual MTU richness was recovered. The most commonly isolated
fungi belonged to the genera Penicillium, Paecilomyces, Phialophora,
and Aspergillus. This culture-based analysis did not reveal significant
differences in fungal richness or number of fungi recovered across sites.
Cluster analysis using DGGE band profiles did not reveal distinctive
groupings of speleothems by sample site. However, canonical
correspondence analysis (CCA) analysis of culture-independent DGGE
profiles showed a significant effect of sampling site and formation type
on fungal community structure. Taken together, these results reveal that
diverse fungal communities exist on speleothem surfaces in Kartchner
Caverns, and that these communities are not uniformly distributed
spatially. Analysis of sample saturation indicated that more sampling
depth is required to uncover the full scale of mycological richness across
spelothem surfaces.

limestone-associated land snail fauna on the oceanic
Hahajima Island (Ogasawara Islands, Western Pacific).

DOI: http://dx.doi.org/10.1111/j.1095-8312.2010.01604.x.
ABS: Because land snails inhabiting the seashore are most likely to be
carried by ocean currents or by attaching to seabirds, land snail fauna on
oceanic islands include species derived from the mainland ancestors
inhabiting the seashore. If habitat use of the island descendants is
constrained by the ecology of the mainland ancestor, the island species
that moved from the coastal habitat to the inland habitat may still be
restricted to relatively exposed microhabitats with high pH, calcium
carbonate-rich substrates, and poor litter cover. We tested this hypothesis
by investigating the association between environmental conditions and
species diversity of seashore-derived species of the endemic land snails
on the oceanic Hahajima Island (Ogasawara Islands). Seashore-derived
species showed higher species richness on limestone outcrops than nonlimestone areas, whereas the other species showed no significant increase
in species richness in limestone outcrops. There was a higher proportion
of seashore-derived species on the limestone ridges than on the soil of
dolines, even in the limestone area. Accordingly, the species derived from
the seashore of the mainland are restricted to microhabitats with poor
vegetation cover, poor litter cover, high pH, and calcium carbonate-rich
substrates, which supports the hypothesis that the inland species on an
island derived from the mainland seashore still prefer environments
similar to the seashore. In addition, the seashore-derived species on the
limestone outcrop include cave-dwellers lacking functional eyes. This
suggests that the probability of colonizing a cave environment is
restricted to seashore-derived species. The findings obtained in the
present study suggest that habitat use of the ancestral lineages can
constrain habitat use of the descendants, even in the oceanic islands with
depauperate fauna. This bias in the species composition on the limestone
outcrop constrains lineages that can colonize and adapt to the inside of
caves, and therefore, habitat use of the ancestral lineages affects the
ability of descendant lineages to colonize novel habitats. KW:

Harmonia axyridis has become notorious as an urban pest in many of the
regions where it has been introduced, despite its numerous contributions
to the biological control of insects injurious to agriculture and
horticulture. Aggregative behavior prior to overwintering leads to
invasions of human habitations as beetles seek refuge from freezing
temperatures. Here we describe the aggregation behavior of native H.
axyridis populations of northeast China that breed in agricultural fields
(mostly corn and rice) and shrub/forest habitats and then migrate through
rural villages in autumn. More than 140000 beetles were collected during
direct observations in 16 villages in five townships in Jilin Province.
Beetles aggregated on dwellings shortly after agricultural harvests,
favoring white walls with southern exposures, the largest aggregations
occurring in villages in mountainous townships at higher elevations. The
sex ratio was consistently female-biased and succinic phenotypes were
more than twice as abundant as melanic phenotypes in all locations. A
special trap compared the relative attractiveness of different surface
colors (white>yellow = black>green>red = natural wood) and potential
baits (corn pollen = honey>caramel = cocoa>milk = blank control). All
aggregations disappeared abruptly just prior to the first frost, whereupon
beetles were discovered sheltering in montane caves with southern
aspects at higher elevations. Villagers reported substantial expenditures
on pesticides in efforts to eliminate beetles from their homes every
autumn. Invasion of human habitations appears to be an intrinsic
tendency of native H. axyridis populations in China, which is the result of
behavioral adaptations for cold-avoidance. KW: Aggregation, Attraction,

based on morphological characters is often a time-consuming and
inconclusive process. Aspects such as morphological stasis and
phenotypic plasticity further complicate their taxonomic designation. In
this study, we demonstrate that the application of DNA barcoding can
alleviate these problems within the Carychiidae (Gastropoda, Pulmonata).
These microsnails are a taxon of the pulmonate lineage and most likely
migrated onto land independently of the Stylommatophora clade. Their
taxonomical classification is currently based on conchological and
anatomical characters only. Despite much confusion about historic
species assignments, the Carychiidae can be unambiguously subdivided
into two taxa: (i) Zospeum species, which are restricted to karst caves,
and (ii) Carychium species, which occur in a broad range of
environmental conditions. The implementation of discrete molecular data
(COI marker) enabled us to correctly designate 90% of the carychiid
microsnails. The remaining cases were probably cryptic Zospeum and
Carychium taxa and incipient species, which require further investigation
into their species status. Because conventional reliance upon mostly
continuous (i. e. nondiscrete) conchological characters is subject to
fallibility for many gastropod species assignments, we highly recommend
the use of DNA barcoding as a taxonomic, cutting-edge method for
delimiting microsnail taxa. KW: Carychiidae, DNA barcoding,

Preliminary observations of the harvestman Leiobunum vittatum found
that individuals rub their bodies against the substrate, presenting the
possibility of chemical marking. To determine whether or not L. vittatum
individuals can detect substrate-borne chemical cues, we compared
responses of L. vittatum males and females to substrate-borne male and
female cues. We found that individuals of L. vittatum do respond to
conspecific cues and that their responses are sex-specific. In response to
substrate-borne conspecific cues, male L. vittatum spent more time,
engaged in more scraping with their sensory legs I, and engaged in
pedipalpal tapping more often in the presence versus absence of
conspecific cues (male and female equally). Furthermore, in the presence
of conspecific cues, males engaged in two behaviors never observed in
females-(a) "fast approach" and (b) "jerking", the latter of which was
never observed in the presence of cricket cues. In contrast to males,
females did not spend more time on conspecific cues, but did spend more
time tapping their pedipalps in the presence of male vs female cues,
suggesting an ability to distinguish between them. A final experiment
explored the possibility that females could discriminate among males of
varying histories of agonistic interactions based upon their chemical cues.
We found no support for this hypothesis. Our results demonstrate that L.
vitattum do respond to conspecific cues, and introduce the possibility that
intraspecific communication may be mediated in part by chemical cues.

Andhracoides shabuddin gen. nov., sp. nov., a new
phreatoicidean isopod (Crustacea, Hypsimetopidae) from
hypogean aquatic habitats in Andhra Pradesh, India.
Zootaxa 2869(May 6):37-53, 9 pl., 32 réf. ABS: A decade-long
survey of ground waters in the state of Andhra Pradesh, India, has so far
yielded over sixty new crustacean taxa, belonging to Copepoda,
Bathynellacea, Amphipoda, Isopoda, and Ostracoda. This paper describes
a new genus and species attributable to the phreatoicidean isopod family
Hypsimetopidae Nicholls, and provides ecological and behavioural
observations. The new taxon was found in Guthikonda Cave, which is
about 8 km from Piduguralla town in the Palnadu area of Andhra Pradesh
State. The species belonging to this clade are unusual in that their
dorsoventrally flattened pleotelson gives them a non-phreatoicidean
appearance. Because the postanal margin is missing, as in other members
of the Hypsimetopidae, this is a superficial similarity rather than
homology with other isopods. Other unusual features include robust blunt
denticles on opposing margins of the pleotelson and protopod of the
uropods. The species in this clade, of which Andhracoides shabuddin
gen. nov., sp. nov. is only the first to be described, are related to
Nichollsia Chopra & Tiwari, found in northeastern India, and to
Pilbarophreatoicus Knott & Halse from the Pilbara region of Western
Australia. The new species differs from its undescribed congeners in
being nearly devoid of dorsal setae; other species of Andhracoides gen.
nov. are much more hirsute. KW: Phreatoicidea, cavernicolous,

information gathering strategy in a blind fish. Journal of
Comparative Physiology A: Neuroethology, Sensory,
Neural, and Behavioral Physiology 197(4, April):321-327.
Blind Mexican cave fish (Astyanax fasciatus) lack a functional visual
system and have been shown to sense their environment using a
technique called hydrodynamic imaging, whereby nearby objects are
detected by sensing distortions in the flow field of water around the body
using the mechanosensory lateral line. This species has also been noted to
touch obstacles, mainly with the pectoral fins, apparently using this tactile
information alongside hydrodynamic imaging to sense their surroundings.
This study aimed to determine the relative contributions of hydrodynamic
and tactile information during wall following behaviour in blind Mexican
cave fish. A wall was custom built with a "netted" region in its centre,
Créé le : 01.01.2011

which provided very similar tactile information to a solid tank wall, but
was undetectable using hydrodynamic imaging. The fish swam
significantly closer to and collided more frequently with the netted region
of this wall than the solid regions, indicating that the fish did not perceive
the netted region as a solid obstacle despite being able to feel it as such
with their pectoral fins. We conclude that the touching of objects with the
pectoral fins may be an artefact of the intrinsic link between pectoral fin
extensions and tail beating whilst swimming, and does not function to
gather information. During wall following, hydrodynamic information
appears to be used strongly in preference to tactile information in this
non-visual system. KW: Cave fish, Navigation, Lateral line, Sensory

Comparative biology of cave-dwelling spitting spiders
(Araneae: Scytodidae): Parental care, cooperative preycapture, cannibalism, natal dispersal and reproductive
behaviour. Raffles Bulletin of Zoology 59(2, August
31):269-284. ABS: Caves are among the most fascinating
environments on Earth. Specialised cave biota provides evidence of
evolutionary adaptations for living under severe conditions. However,
little attention has been paid to the behaviour of cave spiders. In this
study, we compared life history, including maternal care, cooperative
prey-capture, tolerance among siblings, and reproductive behaviour, of fi
ve cave spitting spiders (Scytodidae). Scytodes magna and Guangxi
Scyloxes sp. 1 occur exclusively in the aphotic zone, whereas Scytodes
fusca, S. cavernarum and the Philippines Scytodes sp. 2 are usually found
relatively close to cave entrances, known as the light zone. Like in other
typical spitting spiders, females of S. fusca, S. cavernarum and the
Philippines Scytodes sp. 2 carry their egg-sacs with their chelicerae.
However, here we document for the first time that S. magna and Guangxi
Scyloxes sp. 1 females do not carry their egg-sacs in their chelicerae. We
found that, instead, they hang their egg-sacs on their webs, which is for
the first time documented in scytodids. Although S. fusca is a widespread
species that inhabits a wide range of habitats, we document for the first
time that this species also lives in caves. The five species we studied can
each be characterised as being non-social, but we found a few traits that
deviate from the typical solitary characteristics. These include late natal
dispersal in Guangxi Scyloxes sp. 1 spiderlings and low fecundity in S.
cavernarum. We discuss possible explanations for the solitary habits
adopted by the species we studied. KW: Spitting spiders, solitary,

Differential strategies for maintaining water balance are reported for
female adults of three cave crickets Hadenoecus cumberlandicus, H.
opilionoides and H. jonesi, a species replacement series along the
Cumberland Plateau in the southeastern United States. The distribution of
H. cumberlandicus is much broader than the range of H. opilionoides,
which is much smaller in body size, and that of H. jonesi, which
possesses enhanced troglomorphic (cave dwelling) characteristics. Due to
high net transpiration (water loss) rates and increased activation energies,
H. jonesi and H. opilionoides are more susceptible to dehydration than H.
cumberlandicus. To avoid dehydration, H. opilionoides and H. jonesi
require more moisture than H. cumberlandicus to counter their higher
rates of water loss. The heightened reliance on moisture likely indicates
Publications 2011-1
Page 43 sur 44
that the more troglomorphic H. jonesi and smaller H. opilionoides are
required to spend more time in the moist cave region. Reliance on the
cave for H. cumberlandicus is presumably less, allowing them to function
in epigean habitats for longer periods and disperse to nearby caves, likely
accounting for the more expansive distribution of this cricket. While in
the cave habitat, cave crickets are exposed to water-saturated conditions,
reducing the pressure of dehydration stress the longer a species remains
in this wet environment. This reduced pressure leads to higher water loss
rates as cave confinement increases. We conclude that increasing water
loss rates associated with increasing troglomorphic adaptation in cave
crickets is a side effect of extended residence in stable moist cave
environments. KW: Water balance, Cricket, Hadenoecus, Cave,

1):1545-1562. DOI: http://dx.doi.org/10.1111/j.10958649.2011.03066.x. ABS: Caves and karsts are among the most
threatened ecosystems in the world. They are very fragile, balanced
habitats with high levels of endemic species that are extremely sensitive
to environmental changes. In recent decades, however, threats from rapid
economic growth have increased the need for conservation efforts for
cave-dwelling communities. In addition, difficulties in accessing and
sampling these habitats mean that they remain as one of the least known
ecosystems in the world with modern studies of cave fishes only starting
in China during the 1980s. Here, the current status of cave fishes in China
is reviewed. China is host to the highest number of cave fish species in
the world, with 48 troglobite species out of a total of 101 cave fish
species. All of these cave fish species (one order and three families) and
half of the genera are endemic to China with Sinocyclocheilus being the
most speciose cave fish genus. Species from this genus possess horns and
humpbacks resulting from processes of parallel evolution, but the
function of these features remains unknown. With the exception of
Onychostoma macrolepis distributed in north China, all other species are
found in the karst environment of the Yunnan-Guizhou Plateau.
Sympatric distribution is common, and sometimes several different cave
fish species can be found in the same cave or subterranean river. For this
reason, Chinese cave fishes represent an important evolutionary
framework.
ŽIC (Vesna), TRUESDALE (Victor W.), CUCULIĆ
(Vlado) & CUKROV (Neven), 2011. Nutrient speciation
and hydrography in two anchialine caves in Croatia: tools
to understand iodine speciation. Hydrobiologia DOI:
http://dx.doi.org/10.1007/s10750-011-0686-4. ABS: Despite
iodine being one of the most abundant of the minor elements in oxic
seawater, the principal processes controlling its interconversion from
iodate to iodide and vice versa, are still either elusive or largely unknown.
The two major hypotheses for iodate reduction involve either
phytoplankton growth in primary production, or bacteria during
regeneration. An earlier study intended to exploit the unusual nature of
anchialine environments revealed that iodide is oxidised to iodate in the
bottom of such caves, whereas reduction of iodate occurs in the shallower
parts of the water column. This investigation was made on the hypothesis
that study of the nitrogen and phosphorus nutrient systems within the
caves might offer a bridge between the iodine chemistry and the marine
bacteria which are assumed to be the agent of change of the iodine in the
caves. Accordingly, the hydrography, the nutrient chemistry, and some
further iodine studies were made of two anchialine caves on the east coast
of the Adriatic Sea in Croatia. Iodate and iodide were determined by
differential pulse voltammetry and cathodic stripping square-wave
voltammetry, respectively. Total iodine was determined indirectly, as

iodate, after oxidation of reduced iodine species with UV irradiation and
strong chemical oxidants. Nutrient concentrations were measured by
spectrophotometry. Nutrient profiles within the well stratified water
columns indicate a relatively short-lived surface source of nitrate and
phosphate to the caves, with a more conventional, mid-water, nutrient
regeneration system. The latter involves nitrite and ammonium at the
bottom of the halocline, suggestive of both autotrophic and heterotrophic
microbial activity. High iodate/low iodide deep water, and conservative
behaviour of total inorganic iodine were confirmed in both systems.
Iodate is reduced to iodide in the hypoxic region where nutrient
regeneration occurs. The concentrations of organic iodine were
surprisingly high in both systems, generally increasing toward the
surface, where it comprised almost 80% of total iodine. As with alkalinity
and silica, the results suggest that this refractive iodine component is
liberated during dissolution of the surrounding karst rock. A major,
natural flushing of one of the caves with fresh water was confirmed,
showing that the cave systems offer the opportunity to re-start
investigations periodically. KW: Anchialine systems, Redox speciation,
